How deep are you going to cover this? Sense regulators? Discrete components or integrated circuits? I have used all of them. Good coverage of how they work!
Not much further, frankly. Going deep into this topic would actually drag into a rabbit hole. But if there are questions I'll try to respond. I think that by "sense regulators" you're meaning the sense circuit to provide feedback for the regulation (if I've mistaken, please let me know). Well, actually that is a topic by itself, but ultimately commonly solved with a 4 wires configuration. Even though virtual sensing do exists, such as the one discussed in this application note: www.analog.com/media/en/technical-documentation/application-notes/an126fa.pdf Personally I don't like this solution as it introduces noise. If I need a precise regulation that involves the use of a separate sensing, then very likely I rather don't want to have noise that must be removed through additional capacitors (as mentioned in the application note). It's much better a "mechanical" solution with dedicated cables and clips. Or maybe a compensation proportional to the current (the proportion is rated against the resistivity of the cables) that I see as an overcomplication though. I'm gonna make a couple of *linear* power supplies for my lab, and I definitely will go with the "mechanical" solution. Thanks for your comment mate.
@@AccidentalScience Back in the late 90's I was looking at Linear Technologies application notes for this same type of regulator. Thanks for the refresher. Running the sensing wires as you say the mechanical method is one of the simpler and more rewarding methods to do this. How large of voltage and current are you going to go with your supply? Parallel LM 78,79? Or are you looking for lower noise?
@@KravchenkoAudioPerth I've made a dedicated circuit with buv19 or bux40 final transistor ...pretty old stuff but everything is made out of old new parts laying around. 0...22V 5 amps dual, with aux. fixed 12+5V 1A just using 78xx.
Voltafe regulators are great lets remember all voltage regulators have an error amplifier. Therefore you end up with a amplifier modulating tje load amplifier. So. Not perfect. For hi quality audio ypu must be careful with voltage regulators to keep them from modulating your amplification device
