I need to switch 12V via a 5V signal (microprocessor). However, there is a chance that the output could become a short circuit and I'd like for it to not go pop. Can anyone suggest a circuit that would supply 12V at 350mA from a car battery that when shorted would limit the current to around 1A? I'm starting to think that a LDO regulator with an enable pin would be my simplest solution - any suggestions?
