    I'm working on a bench power supply. I found a few digikey regulators that can only supply 3A max. I've heard you can use a power transistor to increase the current, can anyone show me some links that will show me how to make the regulated circuit or explain how it works to design it myself?

    I was planning on using 3 adjustable regulators, one for +1-20v, a second for -1-20v and the third uses a sp3t switch connected to a trim pot to make vout +5v,+9,+12v. I'm using a +24.5v, 6A power supply.

    if you need anymore info that would help you understand, i can do my best to clarify.
