Simple Linear Adjustable Power Supply Tutorial

Simple Linear Adjustable Power Supply Tutorial (Based Around LM317) by JumperOneTV

Adjustable LM317-based power supplies are an easy way to get custom voltages for your benchtop. Also check out the MIC2941 (used in our breadboard power supply http://www.adafruit.com/products/184) which has some nice benefits such as ultra-low dropout, 1.25A current output and a separate biasing pin. Its nearly a drop in replacement for the LM317 – albeit a little more expensive.
