adjustable power supply question? Using a LM338?
so I'm building a power supply that will have multi power outputs, from surge protected 120, 36v 10a
24v 2.5a, 12v 3a 9v 1a, 12v 1a, 5v usb, and 12v cigarette lighter output.
there is also an adjustable 1.25 to 32v 5 amp, the problem i'm having is no mater what set up I try, I never get more than 1.8 amps out of the LM338, I have an input of 36v 10a, I've tried several diagram , can anyone point me to a diagram that will actually allow a full 5amps to be pulled?
I have the LM338 on a huge heat sink.
