Hi
I am trying to build a 0-1 A variable current source circuit. I built it using LM317 as directed in the following link
LM317 / LM338 / LM350 CURRENT REGULATOR CALCULATOR | Circuit Project Electronic
I used a decade resistance box in place of the variable resistor. the load is around 10 ohms and the current does not go higher than 350mA. The whole circuit heats up and the current changes very drastically. I was hoping that I could find help rectifying the circuit or building a constant current source in any other possible way.
I have approaching deadlines for this project. I would appreciate any help in this regard.
Thank You
Lakshmi
