Im looking to build a simple power supply, possibly using an LM317 .
Does anyone have a schematic to build this power supply ?
Im using it to run the analog / 0-5v signal on a laser, to do some bench testing.
must be variable 0 - 5vdc
the LM317 chip will do 1 amp, so current is no problem.
input will be 120 vac.
Thanks in Advance,
