<br>
I am putting together a power supply for my new 5U case. At first I just <br>
have 7815 and 7915 regulators. But then it occurred to me: would it not <br>
be indeed nice to have both rails fold back if one over currents? to <br>
answer my own question, why yes, yes it would.<br>
<br>
So now to make it work. I thought of using LM317 and LM337s and do a <br>
cross-over thing. Use an op-amp to servo off of a virtual ground set up <br>
with a voltage divider. I am not sure if that will do what I want. I <br>
guess I can try it with the 'L' versions; easier to put into foldback.<br>
<br>
I also thought of using LM723s but that gets complicated in a hurry. <br>
More than I want.<br>
<br>
Thoughts?<br>
