Back in time, I became independent. I started my own business designing electronic test equipment, to test assembled PCB circuits. But I was so poor that I had to use freeware to do the job. I had to create PCB's in the process but the freeware PCB design software only allowed a limited amount of components. It also allowed you to create your own components. So I would design a portion of the PCB layout, and then due to having reached the maximum amount of components allowed, resistors, capacitors, transistors, etc, I created a new component which in truth was a combination of all the components used so far, and their specific layout. Yep, when you are poor, you find a way around everything. Anyhow, one company was so impressed with my work that they hired me full time. Eventually I was also designing high voltage power supplies for neon sings as well as designing the test equipment to test them at the assembled PCB level. Not bad for a grade ten dropout. I had no education in electronics, but was self taught.

Thank you for the video. While there are countless videos on TH-cam, I’ve noticed a common challenge: many channels don’t teach circuits in a way that’s accessible for beginners. It’s hard to grasp why specific components are used. For example, if we try to understand one circuit and then compare it to another with similar functionality, the differences in components can be confusing. Why does one circuit have more components than the other? Take Apple chargers, for instance-what makes them so much more expensive than other mobile chargers? What’s the "magic" behind them? Another issue is that very few creators on TH-cam explain circuit design in detail. They don’t provide practical examples or reasoning behind their choice of components, like why they opted for a diode, capacitor, etc., instead of other alternatives. It would be incredibly valuable to learn the art of transforming a basic circuit into a high-end, quality design.
very inspiring, my guy just summarized my 4 yrs in high school that was spent in studying physics in explaining the fundamentals of electricity under 10 mins, as well as condensed my 5 years in campus that I spent chasing a degree in electronics under the pcb section as well as 2 extra years of entrepreneurship by taking us through the ordering system from jlcpcb.

I went to school for electronics engineering over a decade ago but sadly went into another field of study. I know life...right. I still love watching these videos as a refresher to keep me in the loop or "current" and interested in the science of electricity and electronics. Thank you sir.
That was a brilliant video, I love that PCB design software. I used to do it by hand in the mid 80's and the tapework as well all by hand. We made the artwork twice the size so it was easier to tape then the original would be reduced to half size by copier then ready for printing to PCB. That was the best job I ever had, I even say that over 30yrs later. . All we were given was a circuit design from some big company on a piece of paper, I even had a small diagram on a piece of card. We had to design everything ourselves, I loved it. I lost interest in computers years ago but I would love to learn that system you have there, its brilliant. Good work 😊😊
Wow, this is very thorough! It's gotta be like about 1000 individual steps or so and buttons to push and stuff to do on a computer, to actually build this whole design from nothing, and since I'm not able to comprehend computer stuff and/or how or why they do what all they do, I was honestly completely lost as soon as you started doing stuff on the computer screen instead of on that breadboard, however IF I actually wanted to build this exact thing myself, it looks like I could just watch this entire video again from the 6 minute mark, (after getting a computer AND having someone help me download the software), and then just watch EACH individual step for a few seconds, then pause the video after each step and then do exactly that same thing on the computer, until I finally did ALL of the steps in this video and this project was completely done, which is kinda cool when you think about having that level of detail in a TH-cam video!... If I was to do it that way then this whole project would probably take me (only) at least a few weeks to do exactly like this myself, but that's still WAY faster than I would take to build something like this completely by hand, which I know would be many months for sure!... I just wish I personally knew a friend or somebody who had this exact kind of setup and could show me first hand, step by step, how to do it, but unfortunately I don't have or even know anyone like that who could. Nobody I know who has a computer even cares about building electronic stuff from scratch, they all just go out and buy a pre-made device for whatever they need. So I am the only "electronics nerd" I know, I just don't understand computers at all, because they are way too complicated for me. The closest thing I ever get to operating a computer is my cellphone, (which I am watching this video on and writing this comment on, and is plenty complicated enough for me already, lol!), but everything else electronics-wise, I do and (try to) build totally by hand, old-school style, because that's the only way I've ever been able to understand. All of this newfound "computer" stuff certainly LOOKS cool to at least watch what amazing things that can be done on a TH-cam video, and it seems like it might could even make building stuff much quicker vs. totally by hand, (maybe even easier also, (?), but ONLY IF you know exactly what buttons to push and in what order to push them on the computer itself), but all of that is way above my head unless I have someone else show me and help me every step of the way.
@@EngineeringMindset Yeah, that's all much easier said than done for me. I already can design circuits like this on paper and with a pencil, and on a breadboard like you showed, so understanding and designing a relatively simple circuit like this, that's not the problem. My issue is that I really have NO CLUE how computers work, OR how to "download" software, and definitely not how to actually USE said software. I don't even own a computer, (as close as I get to that is my cellphone, which I saw this video on and I'm writing this comment and reply on), but any computer stuff beyond that is just way too complicated for me to understand! I'm totally "old-school", and I can work on things just fine with a hammer and a screwdriver, (or a soldering iron), but when it comes to using a computer and knowing exactly which buttons to push on it, and when to push said buttons and in what order to make it actually do something useful, I am totally lost! I honestly don't even know how to do ANYTHING on a computer, not even turn one on or off properly... I'm already almost a senior though, so I doubt I'll ever really understand all of this modern computer stuff anyway, so unless I had someone else who already knew this exact thing and who did it themselves already could show me step by step, I'll have to just continue doing all of my electronic tinkering by hand in my garage workshop... But that's OK too I think, because at least I still (try) to fix things that break or wear out... Most people nowadays are just of the totally wasteful mindset of "Just throw it away and buy a new one!", and that kind of thinking really disgusts me, so at least I'm one who is still actually interested in how basic electronic and electrical stuff works. I don't personally know anyone else who even cares at all about how electronic/electrical stuff works, unfortunately. Everyone else I know, (including all of the younger kids I know), is just of the "throwaway society", which isn't too good for the future of the planet and future generations, in my opinion!
This is the best Electronics and Engineering channel on TH-cam. Without a doubt. All videos are clear, objective so as not to leave any "loose ends" that could create confusion. I was very happy to find this channel. Many questions that I have come here and resolve. That simple. Thank you !🙏🙏🙏🙏🙏🙏
Designing a voltage regulator is not as hard as it seems. Especially, if you have a basic understanding of circuits and some electrical components. After watching a few online tutorials, I decided to give it a try. The end result was a functioning voltage regulator circuit that met my needs. I must admit that I was motivated to design my own voltage regulator after watching one of your videos. Your explanation was outclass.
This is one of the best videos I've ever watched 🔥🔥. You killed many birds with one stone, by explaining different aspects in a way that makes the process seam easy, starting from components' operation, circuit design, to PCB fabrication. Lots of love for the great work you're doing.
Not only does this video tell us shit, but the sponsor stuff was informative too. Top marks for turning the sponsor ad into useful info too. Unique skill. It's only one person, but you've got another follower.
absolutely fantastic way to transfer knowledge, well done, so .... comprehensive. esp love the 'hey this might work too for this reason, but this is fine' element. teaches me so much more as it gives me a scale of the subject/component/concept
This is the BEST video you have ever made! I love all of your videos but learning to make your circuits a reality is the most amazing thing ever you have no idea!!!
Paul thanks for everything. I have learned lots of useful things about my profession more than I learned from university. Your channel is AMAZING... and please make a video about solar energy systems🙏
I never knew how a voltage regulator worked before I started watching your channel. I also learned about linear regulators and how to choose the right one for a specific application. I now know more about my profession than I ever did from university. Thank you for making these videos!
you will learn how to make a 5V regulator using capacitors, LM7805 regulator and Schottky diode. This circuit works by converting the unregulated voltage from the battery into a regulated 5V output. The capacitors smooth out the voltage fluctuations, while the LM7805 regulator ensures a stable 5V output. The Schottky diode protects the circuit from reverse polarity connection and also increases efficiency.
You know when students tune out to avoid brain pain overdrive leaving a faint voice talking to somebody , because your explanation animation style doesn't lack the obvious skill and experience in educating even lost causes who comment they know nothing about electronics. But now show interest because now they unknowingly got lead skilfully towards understanding the maze of electronics. Very interesting and entertaining for the beginner , thanks a heap cos l shall return often ..
Oh, nooo... I was looking for such a channel for long. After watching the video I immediately subscribed. Please keep all your videos as simple as possible.
Great video! It would be great to explain to beginners the principle of why the values of those capacitors are used. Or else, you are just teaching someone to copy a design and not design it themselves.
used a 1.00uF capacitor instead of the 0.22 since i didn’t have one, still works perfectly. Powered with a 9V battery and output is 5.01V as desired. Made a similar circuit before without a diode and with only 2 capacitors instead of 4.
You can connect DC to a 7805 directly, no need for any extra components, those are just recommendations, but I've only ever used it on it's own and a battery for any logical gates circuits, which can only work with 5v.
I remember when I was in middle school, I followed a tutorial on how to make a voltage regulator and housing everything in an altoids tin. It had the voltage regulator and just a resistor. I'm pretty sure I shorted the whole thing by either having the tin short circuit the whole thing, or I reversed the inputs. Anyways, I'm 27 now, have a degree in physics and a profession. I think this will be my first full fledged personal electronics project.
Nice videos, and also really well explained. Please continue making this kind of videos that really helps a lot to those who want learn something new the best vibes for you
In this video, we're going to take a look at a voltage regulator circuit. This is a very important circuit, and it's used to maintain a constant voltage output despite changes in the input voltage. This is useful for things like powering microcontrollers, or other sensitive electronics. The basic principle of the voltage regulator circuit is simple. We have an input voltage, which is applied to the Vin pin of the regulator. The regulator then outputs a constant voltage on the Vout pin. This voltage is regulated by the feedback resistor Rfb. The regulation of the output voltage occurs because of the way that transistors Q1 and Q2 are connected. Transistor Q1 acts as an amplifier, while transistor Q2 acts as a switch. When Vin is greater than Vout, transistor Q1 is turned on and transistor Q2 is turned off.
This is next level tutoring right here - if this kind of quality content existed when i was meandering my way through grade school, I would have had my seat firmly planted in those classroom benches instead of chasing dirty $kankz and booze 😂
Remember that W=V*I. Meaning, if you have higher voltage input (say 24V) but output is only 5V and you're drawing only 0.2A then the linear voltage regulator has to dissipate about ( 24V - 5V ) * 0.2A = 3.8W as waste heat. It will get quite hot quite fast. Times like that - consider if buck regulator would be better option, if not for the noise/EM interference that accompanies it. I would turn the voltage regulator 90 degrees and place it near edge. Another possibility would be placing it flat on the other side (there are more options). It all depends on how you are planning to connect it to the heatsink and/or how much heat you need to dissipate.
Based on the datasheet, at 25°C ambient, you can draw 6.58W. That's 1.32A. Keep in mind that's at 25V. If your input was 12V or 9V, which is typical, you can easily achieve 1.5A without a heat sink. However, I would use a heat sink to dissipate heat through a sealed case to reduce heat building up, which might affect other components.
I am old and impressed with your videos, but as I said it’s been 50 years since I built a P. C.U. At 17 years of age.. since our government shut down my main supplier of kits . I want to build a lazier communication Device, not available in the USA Can you recommend a kit co. That can, at least show a kit design that I can make myself. Love your site, clear and understandable.
A voltage regulator circuit is a great way to ensure a steady flow of power to your project. However, if you're using an AC adapter to power your project, you'll need to use a bridge rectifier to protect your regulator from polarity reversal. Without a bridge rectifier, your regulator may be damaged if the polarity of the input voltage changes.
You explained this better than all the professors in my supposedly "TOP" University. Have always been interested in these but got impotent people to learn from sadly.
it's an outstanding tutorial everything is sound thump up bro.....i did it 20 yrs ago n it came up straight away well done cant wait what else I will discover.
Great vid, I was looking for such a device, we have gas BBQs that I installed with micro solar panels to charge the igniter, I ran into a problem when the cloud cover changed to output voltage it would trip out the controller for the gas flow, I think this might be the answer to keep a constant voltage from the battery to the units circuit. Thanks from downunder 🇦🇺👍
Making custom PCBs has changed so much since when I was younger. I remember being 12 years old and I had to hand draw the tracks with an etch resist pen, onto copper clad board. Then I would etch the copper, using a spare plastic takeaway tub, filled with ferric chloride. Finally, I'd drill the PCB with a hand operated drill and a .8mm bit. Then I would use engine de-greasant to remove the remaining etch resist pen ink from the copper tracks. Then the board was ready for soldering. I didn't have the luxury of the green solder mask, or the professional white text. It was often difficult, because I had to mentally reverse the circuit, as I was drawing the copper track layout on the bottom side of the board. Often times, I'd get it wrong.
Take note that the capacitors have values based on the expected loads/ power deraws of the circuit, also make sure the diodes use have a smaller break voltage then the voltage source u are using
In awe and amazement... Although I'm still in the model A technology... I understood everything you said and am blown away at the computer designing. That's like SR71 advancements to me. 🚲↗️🚗↗️🚀........↗️
ok, that's creepy. i'm not into electronics but from time to time i try some stuff and just a few hours ago i decided i need something to generate custom volages for testing purposes
Depends if you did any online searches on the device(s) you are signed into TH-cam with...cookies and search history give a lot of weight to what is advertised to you depending on your ad choices preferences and TH-cam ad preferences. Would be less likely to happen if you ask for ads to not be personalised and if you aren’t signed in to TH-cam on the device you perform online searches with.
Loved the video, but this should be titled "how to use a voltage regulator". This did nothing to explain how a voltage regulator functions and operates, mostly "it does this and here's how to use it" which is still valuable but a misleading title.
Yeah buddy i totally agree with you i thought he is gonna design a new one and build a prototype then test it and show us. This is also a great video apart from misleading title
Nice video--and appreciate you providing the PCB files etc. I actually built it---A couple of observations---first--I always use a heatsink on the 78xx series---and the PCB doesn't have provisions for one--Second--the files are from Altium--which are hard to convert and alter if you use a different PCB design platform. I ultimately just used the stock file you provided and sacrificed one of the caps---which didn't seem to affect noise off battery supply--Finally--I used this to power an Arduino--and thus used a 7809 because Arduino has its own VREG and requires 7-12 volts for accurate voltage stability--also--by using a 9v 78xx--you dissipate the heat across two Regs--3 volts (assuming 12v supply)on this board/reg, and another 4v across Arduino reg. If you run this with a 12v supply at 1 amp--you will find it shuts down quickly due to thermal protection....I mean these comments constructively and always appreciate you videos!
I wanted to point out a few things wrong with this PCB. First off, those traces will not stand the current without a significant temperature rise. Unless you meant for the traces to act like fuses then I would increase the width. Next, the diode you use for reverse polarity protection doesn't have much better vf at the currents you were using. While you did (at least I think) purposely choose a diode with low leakage current the vf is the thing you want to focus on in this circuit and the diode doesn't have that great of a vf. And, why not just use a p-channel MOSFET for reverse polarity protection? Furthermore, having the capacitors right next to the regulator probably isn't good for them. If you can even reach current levels that generate a substantial amount of heat without the traces burning out. Please make a new video that teaches people good design ideas and not just use autorouter.
Great shot of the led burning out 65s into the video. I totally agree that the bonding wires melted due to the high current, but someone who didn't know any better might come to the conclusion that the wire was disintegrated by the intense green death ray.
I don't think putting a 7805 on a circuit board can really be called "designing a voltage regulator". You bought a voltage regulator and put some filter caps on it.... poorly chosen ones, badly laid out, and with no heatsink, which means you get maybe a third of the current that the 7805 can support. This is a bit like going out and buying a motherboard and CPU, putting them into a box, and claiming you've "designed" a computer.

It's gotta be like about 1000 individual steps or so and buttons to push and stuff to do on a computer, to actually build this whole design from nothing, and since I'm not able to comprehend computer stuff and/or how or why they do what all they do, I was honestly completely lost as soon as you started doing stuff on the computer screen instead of on that breadboard, however IF I actually wanted to build this exact thing myself, it looks like I could just watch this entire video again from the 6 minute mark, (after getting a computer AND having someone help me download the software), and then just watch EACH individual step for a few seconds, then pause the video after each step and then do exactly that same thing on the computer, until I finally did ALL of the steps in this video and this project was completely done, which is kinda cool when you think about having that level of detail in a TH-cam video!... If I was to do it that way then this whole project would probably take me (only) at least a few weeks to do exactly like this myself, but that's still WAY faster than I would take to build something like this completely by hand, which I know would be many months for sure!...
I just wish I personally knew a friend or somebody who had this exact kind of setup and could show me first hand, step by step, how to do it, but unfortunately I don't have or even know anyone like that who could. Nobody I know who has a computer even cares about building electronic stuff from scratch, they all just go out and buy a pre-made device for whatever they need. So I am the only "electronics nerd" I know, I just don't understand computers at all, because they are way too complicated for me. The closest thing I ever get to operating a computer is my cellphone, (which I am watching this video on and writing this comment on, and is plenty complicated enough for me already, lol!), but everything else electronics-wise, I do and (try to) build totally by hand, old-school style, because that's the only way I've ever been able to understand. All of this newfound "computer" stuff certainly LOOKS cool to at least watch what amazing things that can be done on a TH-cam video, and it seems like it might could even make building stuff much quicker vs. totally by hand, (maybe even easier also, (?), but ONLY IF you know exactly what buttons to push and in what order to push them on the computer itself), but all of that is way above my head unless I have someone else show me and help me every step of the way.
Or, you just download the free file, upload it to the pcb website and order the board to your house without having to learn to design it
@@EngineeringMindset Yeah, that's all much easier said than done for me. I already can design circuits like this on paper and with a pencil, and on a breadboard like you showed, so understanding and designing a relatively simple circuit like this, that's not the problem. My issue is that I really have NO CLUE how computers work, OR how to "download" software, and definitely not how to actually USE said software. I don't even own a computer, (as close as I get to that is my cellphone, which I saw this video on and I'm writing this comment and reply on), but any computer stuff beyond that is just way too complicated for me to understand! I'm totally "old-school", and I can work on things just fine with a hammer and a screwdriver, (or a soldering iron), but when it comes to using a computer and knowing exactly which buttons to push on it, and when to push said buttons and in what order to make it actually do something useful, I am totally lost! I honestly don't even know how to do ANYTHING on a computer, not even turn one on or off properly...
I'm already almost a senior though, so I doubt I'll ever really understand all of this modern computer stuff anyway, so unless I had someone else who already knew this exact thing and who did it themselves already could show me step by step, I'll have to just continue doing all of my electronic tinkering by hand in my garage workshop... But that's OK too I think, because at least I still (try) to fix things that break or wear out... Most people nowadays are just of the totally wasteful mindset of "Just throw it away and buy a new one!", and that kind of thinking really disgusts me, so at least I'm one who is still actually interested in how basic electronic and electrical stuff works. I don't personally know anyone else who even cares at all about how electronic/electrical stuff works, unfortunately. Everyone else I know, (including all of the younger kids I know), is just of the "throwaway society", which isn't too good for the future of the planet and future generations, in my opinion!
This is the best Electronics and Engineering channel on TH-cam. Without a doubt. All videos are clear, objective so as not to leave any "loose ends" that could create confusion. I was very happy to find this channel. Many questions that I have come here and resolve. That simple.
Thank you !🙏🙏🙏🙏🙏🙏
Love the way you teach😍: first explaining circuit, then design, then using design app.
Very good, I hope you continue this way. 🙏
You sir are an excellent teacher, thank you for time taken to put this and your other videos together and sharing with all, awesome👍👍
The explanation was outclass. You motivated me to design my own voltage regulator like you did. Thanks man. God bless you
Designing a voltage regulator is not as hard as it seems. Especially, if you have a basic understanding of circuits and some electrical components. After watching a few online tutorials, I decided to give it a try. The end result was a functioning voltage regulator circuit that met my needs.
I must admit that I was motivated to design my own voltage regulator after watching one of your videos. Your explanation was outclass.
This teacher is much better than my school teacher. Best electronic yt channel on youtube. Thank you.
To put it simply, you're brilliant!
The best circuit designing A to Z using Altium I have ever seen on TH-cam 👍🏻👍🏻
This is one of the best videos I've ever watched 🔥🔥. You killed many birds with one stone, by explaining different aspects in a way that makes the process seam easy, starting from components' operation, circuit design, to PCB fabrication. Lots of love for the great work you're doing.
Not only does this video tell us shit, but the sponsor stuff was informative too. Top marks for turning the sponsor ad into useful info too. Unique skill. It's only one person, but you've got another follower.
absolutely fantastic way to transfer knowledge, well done, so .... comprehensive. esp love the 'hey this might work too for this reason, but this is fine' element. teaches me so much more as it gives me a scale of the subject/component/concept
Incredible video ... i am not an engineer but i watch these videos .. because i really love it. Thanks for posting them. 🤗
great tutorial. explaining the functionality of each component was the best part form me. thank you for sharing
This is the BEST video you have ever made! I love all of your videos but learning to make your circuits a reality is the most amazing thing ever you have no idea!!!
Thank you so much ! but we need more projects like this in order to apply what we have learned ! I think everyone agree on that :D
You are the reason why I am so passionate about being an electrical engineer.
Paul thanks for everything. I have learned lots of useful things about my profession more than I learned from university. Your channel is AMAZING... and please make a video about solar energy systems🙏
I never knew how a voltage regulator worked before I started watching your channel. I also learned about linear regulators and how to choose the right one for a specific application. I now know more about my profession than I ever did from university. Thank you for making these videos!
you will learn how to make a 5V regulator using capacitors, LM7805 regulator and Schottky diode. This circuit works by converting the unregulated voltage from the battery into a regulated 5V output. The capacitors smooth out the voltage fluctuations, while the LM7805 regulator ensures a stable 5V output. The Schottky diode protects the circuit from reverse polarity connection and also increases efficiency.

You know when students tune out to avoid brain pain overdrive leaving a faint voice talking to somebody , because your explanation animation style doesn't lack the obvious skill and experience in educating even lost causes who comment they know nothing about electronics. But now show interest because now they unknowingly got lead skilfully towards understanding the maze of electronics. Very interesting and entertaining for the beginner , thanks a heap cos l shall return often ..
A small solar panel as the input voltage would be sweet.
Probably need a few solar cells, need to input +7V minimum, but it would work
Voltage regulators are inefficient and only work with higher voltage. Think of it this way "Where does all the extra voltage go?
@Joachim Shekelberg wasted electricity is never a good thing
@Joachim Shekelberg what circuit do you use , any linear regulator always have dropout votage
Not realy, this curcuit doesnt take advantage of a solar panel power changes trow the day
You are a brilliant mind 🧠 all the way from South Africa, much appreciated.
Great video, really i have get benefit of it. Next video we need overcurrent protection circuit .
Thank you so much for your exerts.
Just wanted to pop in real quick to shout out, I ABSOLUTELY LOVE THIS CHANNEL!! 😃👍🏻
Dear God. That software tutorial was like learning German. Time for me to hire a tutor! Lol
Like eagle software
That software was just bad, I'm sure there are better ones that are more user friendly.
@@Othman1992on and don't cost an arm and a leg, like Altium
Oh, nooo... I was looking for such a channel for long. After watching the video I immediately subscribed. Please keep all your videos as simple as possible.
Great video! It would be great to explain to beginners the principle of why the values of those capacitors are used. Or else, you are just teaching someone to copy a design and not design it themselves.
Impressive explanation...7805 always remain the top priority and almost have one since 2010, when i first started my own design.
used a 1.00uF capacitor instead of the 0.22 since i didn’t have one, still works perfectly. Powered with a 9V battery and output is 5.01V as desired. Made a similar circuit before without a diode and with only 2 capacitors instead of 4.
You can connect DC to a 7805 directly, no need for any extra components, those are just recommendations, but I've only ever used it on it's own and a battery for any logical gates circuits, which can only work with 5v.
@@Freixenetynt yes i know. the capacitors just help filter out any noise in the circuit
I remember when I was in middle school, I followed a tutorial on how to make a voltage regulator and housing everything in an altoids tin. It had the voltage regulator and just a resistor. I'm pretty sure I shorted the whole thing by either having the tin short circuit the whole thing, or I reversed the inputs. Anyways, I'm 27 now, have a degree in physics and a profession. I think this will be my first full fledged personal electronics project.
Nice videos, and also really well explained. Please continue making this kind of videos that really helps a lot to those who want learn something new the best vibes for you
In this video, we're going to take a look at a voltage regulator circuit. This is a very important circuit, and it's used to maintain a constant voltage output despite changes in the input voltage. This is useful for things like powering microcontrollers, or other sensitive electronics.
The basic principle of the voltage regulator circuit is simple. We have an input voltage, which is applied to the Vin pin of the regulator. The regulator then outputs a constant voltage on the Vout pin. This voltage is regulated by the feedback resistor Rfb.
The regulation of the output voltage occurs because of the way that transistors Q1 and Q2 are connected. Transistor Q1 acts as an amplifier, while transistor Q2 acts as a switch. When Vin is greater than Vout, transistor Q1 is turned on and transistor Q2 is turned off.

Thanks for the great tutorial, I just ordered the voltage regulator PCB and my students will be building them soon. Thanks again.
This is next level tutoring right here - if this kind of quality content existed when i was meandering my way through grade school, I would have had my seat firmly planted in those classroom benches instead of chasing dirty $kankz and booze 😂
one of the best videos i've ever watched.
There should be a heatsink attached with the voltage regulator though.
Remember that W=V*I. Meaning, if you have higher voltage input (say 24V) but output is only 5V and you're drawing only 0.2A then the linear voltage regulator has to dissipate about ( 24V - 5V ) * 0.2A = 3.8W as waste heat. It will get quite hot quite fast. Times like that - consider if buck regulator would be better option, if not for the noise/EM interference that accompanies it.
I would turn the voltage regulator 90 degrees and place it near edge. Another possibility would be placing it flat on the other side (there are more options). It all depends on how you are planning to connect it to the heatsink and/or how much heat you need to dissipate.
Based on the datasheet, at 25°C ambient, you can draw 6.58W. That's 1.32A. Keep in mind that's at 25V. If your input was 12V or 9V, which is typical, you can easily achieve 1.5A without a heat sink. However, I would use a heat sink to dissipate heat through a sealed case to reduce heat building up, which might affect other components.
I am old and impressed with your videos, but as I said it’s been 50 years since I built a P. C.U. At 17 years of age.. since our government shut down my main supplier of kits . I want to build a lazier communication Device, not available in the USA
Can you recommend a kit co. That can, at least show a kit design that I can make myself.
Love your site, clear and understandable.
For polarity protection, I'd use small bridge rectifier. Then you can even supply ac to circuit.
Could you please help me how to add few more components into it and how can I get multiple outputs from it from different points. For eg 5v 3v etc
A voltage regulator circuit is a great way to ensure a steady flow of power to your project. However, if you're using an AC adapter to power your project, you'll need to use a bridge rectifier to protect your regulator from polarity reversal. Without a bridge rectifier, your regulator may be damaged if the polarity of the input voltage changes.
@@SFORSANDEEP you need a 2510 bridge rectifier at the input side and a variable resistor or potentiometer at the output side

Have always been interested in these but got impotent people to learn from sadly.
it's an outstanding tutorial everything is sound thump up bro.....i did it 20 yrs ago n it came up straight away well done cant wait what else I will discover.
Great vid, I was looking for such a device, we have gas BBQs that I installed with micro solar panels to charge the igniter, I ran into a problem when the cloud cover changed to output voltage it would trip out the controller for the gas flow, I think this might be the answer to keep a constant voltage from the battery to the units circuit.

This was a great video about regulating voltage with the 7805. I wonder if you are also going to make a video about buck converters or SMPS.
Plenty more coming
You're best teacher I've ever seen, please continue and make a video about more complex PCBs...regards
Buck boost modules vs regulator ics. Need a lecture on this
Making custom PCBs has changed so much since when I was younger.
I remember being 12 years old and I had to hand draw the tracks with an etch resist pen, onto copper clad board.
Then I would etch the copper, using a spare plastic takeaway tub, filled with ferric chloride.
Finally, I'd drill the PCB with a hand operated drill and a .8mm bit. Then I would use engine de-greasant to remove the remaining etch resist pen ink from the copper tracks.
Then the board was ready for soldering.
I didn't have the luxury of the green solder mask, or the professional white text.
It was often difficult, because I had to mentally reverse the circuit, as I was drawing the copper track layout on the bottom side of the board. Often times, I'd get it wrong.
A 7805 in a PCB without space for a heatsink it's pretty useless
i am a beginner..
i want to know whether what you said means that he did it the wrong way and shouldnt have used that ic without heatsink?
Nope. Heat sink not needed for small currents and lower input voltages.
@@kennmossman8701 Current less than 500 mA and input voltages less than 7.5 volts.
@@kennmossman8701 7v
Kenn Mossman so i could just use a stepdown converter instead if my loads is big..
I have never seen a flawless video, today made me do 🎉
Take note that the capacitors have values based on the expected loads/ power deraws of the circuit, also make sure the diodes use have a smaller break voltage then the voltage source u are using
@@kennmossman8701 almost never but i had an apkication where it mattered

You my brother, have the best explanations in the world. May you be blessed for life !
Nowadays, linear voltage regulator becoming obsolete, switch mode is present and future
It is completely defined and detailed. Big thanks..
Loved the video, but this should be titled "how to use a voltage regulator". This did nothing to explain how a voltage regulator functions and operates, mostly "it does this and here's how to use it" which is still valuable but a misleading title.
Yeah buddy i totally agree with you i thought he is gonna design a new one and build a prototype then test it and show us. This is also a great video apart from misleading title
Yeah, I thought he was gonna describe the internals of the IC, not how to connect an IC
Nice video--and appreciate you providing the PCB files etc. I actually built it---A couple of observations---first--I always use a heatsink on the 78xx series---and the PCB doesn't have provisions for one--Second--the files are from Altium--which are hard to convert and alter if you use a different PCB design platform. I ultimately just used the stock file you provided and sacrificed one of the caps---which didn't seem to affect noise off battery supply--Finally--I used this to power an Arduino--and thus used a 7809 because Arduino has its own VREG and requires 7-12 volts for accurate voltage stability--also--by using a 9v 78xx--you dissipate the heat across two Regs--3 volts (assuming 12v supply)on this board/reg, and another 4v across Arduino reg. If you run this with a 12v supply at 1 amp--you will find it shuts down quickly due to thermal protection....I mean these comments constructively and always appreciate you videos!
I wanted to point out a few things wrong with this PCB. First off, those traces will not stand the current without a significant temperature rise. Unless you meant for the traces to act like fuses then I would increase the width. Next, the diode you use for reverse polarity protection doesn't have much better vf at the currents you were using. While you did (at least I think) purposely choose a diode with low leakage current the vf is the thing you want to focus on in this circuit and the diode doesn't have that great of a vf. And, why not just use a p-channel MOSFET for reverse polarity protection? Furthermore, having the capacitors right next to the regulator probably isn't good for them. If you can even reach current levels that generate a substantial amount of heat without the traces burning out. Please make a new video that teaches people good design ideas and not just use autorouter.
See my new MOSFET explained video here➡️: th-cam.com/video/AwRJsze_9m4/w-d-xo.html
Great shot of the led burning out 65s into the video. I totally agree that the bonding wires melted due to the high current, but someone who didn't know any better might come to the conclusion that the wire was disintegrated by the intense green death ray.
I don't think putting a 7805 on a circuit board can really be called "designing a voltage regulator". You bought a voltage regulator and put some filter caps on it.... poorly chosen ones, badly laid out, and with no heatsink, which means you get maybe a third of the current that the 7805 can support. This is a bit like going out and buying a motherboard and CPU, putting them into a box, and claiming you've "designed" a computer.
If you were my teacher in school, every student would be a genius
Charging a phone this way is disgustingly inefficient. You need to mention that a buck converter would have worked much better for this application.
Today I learned how to design a PCB board and get it made. Thanks so much. :)
this provides an amount of knowledge equivalent to 5 years of my uni courses.
