Hello all,
I am using 7805 regulator from 12V source to power a modem. Current drain is about 500 mA. I also want to use a AC adapter (5V 1 Ampere model) at the same time. In other words when there is a electricity modem gets its voltage from AC adapter and during outage it gets from 12V battery via 7805 regulator.
So I am thinking of simply hooking the AC adapter in parallel with 7805 output. Would that be a wise move? Thanks.
