Well I have a candy tin and wanted to put a 9v (battery) input and a 12v (car) input. And have it go out to a female USB port. I need one of these **broken link removed** So it will regulate the voltage to 5v. It is rated for 5v to 18v so I figured no problem having 2 input voltages (only going to use one at a time of course) and would have a switch so you can select 12v, 9v or off. I would like to include a on LED so I figured I would put that behind the voltage regulator. Do you think this is possible do I need any capacitors to keep the power "clean"?
Any help would be appreciated.
