Quick question about an LM317

post #1 of 3
Thread Starter 


This is a simple Constant Current Setup.
Do I need to use a power resistor or will a 1/4w one work?
(Does the current come from the vout pin or the adj pin?)

I did a search and came up with this page that outlines the calculations for resistor size and power rating based on what you want to power with the constant current supply.

Based on your application, the 1/4W resistor may or may not be appropriate.
