I am planning a LCD display application for my car using a PIC. I want it to be powered by the car's 12v system, and Im worried about electrical noise, surges, etc.
I was going to use a LM7805 voltage regulator and Capacitor to drop it to 5v. Is there anything else I should use to prevent noise or protect the circuit in other ways? Any added components have to be pretty small (TO-92 or similar size).
Im a bit of a newbie so specific part numbers would be helpful. Thanks.
