hello guys. i want to make a "power supply" for my tablet, that i will use in my car. my tablets AC power supply, says output: 5v 2A.
what i want to do, is take the 12v unregulated from the battery, then use a voltage regulator of 5v , and connect that output, to the tablet??
what additional circuit, would i need to add before and after the regulator, to protect the whole thing, from the car's harsh environment (spikes etc)?
P.S ( I prefer linear regulator, than a switcher, because efficiency is not neccecery, and i don't want the switchers noise in the system... )
