lm317 variable power supply circuit project

Posted on Feb 5, 2014

As you can see in the circuit diagram this LM317 power supply electronic project require few external components. The input voltage required by this electronic project must be between 8 and 35 volt, and will provide a variable output voltage over a wide range, from 1. 8 volts up to 32 volts. C1, C4 capacitors must be a solid tantalum type and
