I have found a Usefull LM regulator (LM138) wich will give me 5amps.
the problem is it is adjustable sow it means it doesn´t sees ground??
Is it true that if the input voltage changes on the part, that the output is also changed????
Wich little chip could make it auto adjustable?
An opamp maybe?
could someone draw me up a small sheme?
Tks
