Hi all;
I need a power supply that will give me 12v, 9v, and 5v. I have a 15v
transformer already, with 7812, 7809, and 7805 regulators. Now, should I
hook the regulators up in series (i.e., with the output of the 7812 feeding
the input of the 7809 which would feed the input of the 7805), or in
parallel (i.e., inputs of all 3 regulators connected to the secondary of the
transformer)?
I can't see that one way or the other would make much difference, but I
thought I should check to see if there are advantages/disadvantages to
either method.
Thanks
