Need regulated 12v output to handle 70A
(OP)
I need a circuit that will take in 14 v and put out a regulated 12v with a max load of 70A for 4 minutes. Any ideas of what circuit I can make?

RE: Need regulated 12v output to handle 70A
Depending what mean "regulated" 12V - what % is allowed for application, one simple way and cheap is to put 2 or 3 series power diodes to obtain 11.9 - 12.4V output voltage. Large heatsink may be needed. If is not acceptable you'll need a converter, maybe with transformer 1:1 or even slightly higer to overcame this small input-output voltage difference and by PWM control to obtain a very stable 12V output.

Most of the current consumers I can conjecture that have a nominal voltage of 12, are actually intended for use in automobiles, where the system voltage at which devices are expected to operate ranges between 8-ish and 14.5-ish volts.
