Hi guys, I've been reviewing a circuit design which was going to run on dual power supply (power side and MCU control side) and now intend to put the control circuitry which is essentially a pic powered on a 78L05 (or equivalent) on the main supply that is on 24/7.
I'm now going to have the 78L05 reg and associate caps powered off 12 V and the pic off 5 V 24/7, what sort of life expectancy can I be looking at ?. I suppose I'm concerned as I still treat the pic as a computer versus a simple digital chip
