EEVblog #222 – Lab Power Supply Design – Part 2

PART 1 is HERE: https://www.youtube.com/watch?v=CIGjActDeoM Part 2 of Dave’s constant current linear regulated lab power supply design. An in-depth look at the LT3080 datasheet, the LM334 current source, and a few more circuit tweaks before it’s ready to build in the next episode to see if it works! And thanks …

EEVblog #221 – Lab Power Supply Design – Part 1

Dave shows you how to design a simple constant current and constant voltage lab power supply that can be either software (PIC/AVR et.al microcontroller) or traditional pot controlled. Starting with the venerable LM317, and ending up with an LT3080 solution, and the some thought processes that go into it all. …

EEVblog #215 – Gaussian Resistors

Just how far out is that +/-1% metal film resistor you are using? Is it just random? Does it follow the classic bell shaped Gaussian response? What are the odds of getting one that’s spot on, or right out at the limits? Dave thought he’d find out, the hard way… …
