Adjust potentiometer, output voltage from 1.25v-37v with max 40v power supply. The circuit is capable of many different voltage levels depending on your work requirements
- Just 1 IC LM317 and a few simple components you can adjust the current up to 1.5A. If you need a higher current, add 1 more transistor
- The circuit is simple but has high reliability and accuracy.
