Hopefully a simple question. I'm still not comfortable reading the datasheets without an advisor. If somebody could please advise me, I would be grateful.
I have a pump which requires 12VDC, 1.4A.
I want to power the pump with a wall adapter (what some folks call a "wall wart") that gives 20VDC 1.0A.
Now, there is a regulator called an LM7812, that will give a regulated 12VDC output. The headline on the datasheet (from Fairchild) describes this component as a "1A regulator". But later, the datasheet claims a maximum 2.2A peak current.
If I put 20VDC 1.0A into an LM7812, do I get 12VDC 1.6A out?
Thanks for your help.
