High Current Voltage Regulation

In regard to this page, I have drawn up a couple of 78xx high current circuits you might like to consider. Ken Weaver, 17th August The benefit of this first schematic is that the output is actually regulated; the PNP is fully in the feedback loop.

I have since switched to using the better LM regulator so that I can adjust the voltage and it is far more reliable than the 78xx. There are 12 items available.
