Series Voltage Regulator (4 - Regulators)

Derivation of all design equations for series voltage regulator with a pass transistor and zener diode. This remedies some shortcomings with a simple zener shunt regulator. This is the version without negative feedback. In a subsequent video, I'll continue with an improved version containing negative feedback. This is a continuation of a series of videos about power supply design/voltage regulators.

Happy new year prof. Always great to see these videos. It brings back memories. Take care and stay healthy as always.

Awesome, Happy New Year !.......cheers.

Thank you for the video.
In the example in my opinion is important also to observe that the transistor, in the worst case, have to absorb (and dissipate) 8W

First video lecture of 2024! Happy new year

Professor, could you create a series of videos covering RF, comparators, ADCs, DACs, mixers, and related topics

Professor, you said that the maximum wattage that the R sub s resistor would see is .977 watts so you chose a 1 watt resistor. I was taught that choosing a resistor wattage at least 1 & 1/2 times the expected wattage is good practice in design. I would spec out a 2 watt resistor for this. Am I wrong?

Given that most real components specify their maximum wattage rating in the presence of crazy heat sinking and airflow, I'd recommend mentioning to students that they derate their components by a half if trying any experiments based on these calculations, unless they've also done a bunch of thermal transfer calculations.

Why didn't you calculate Rs value when Vin=18V
