i been trying to find a lm 317 type chip that can handle above 3 amps handeling 5 to 6 would be nice and ajust it with a pot ? any takers on other options for an ajustable power supply build ?
My answer is, if you don't mind some heat, the LM338K.
And maybe you are interested in developing an Arduino controlled regulated power supply, with current limit and constat current features. I´m playing with this proyect for a while.
