Simple 5v PSU (battery Powered)
Hello,
this is my first instructable a longgg timmeee, and in that time, I have learned much, such as soldering is a good thing, melting plastic is a bad thing and that using the correct components mounted on a board is a good thing.
But less of that and on with the instructable.
Components
Components--
9v Battery Clip OR DC Jack
9v Battery OR ~9v AC-DC transformer
10uf capacitor
0.1uf capacitor (or 100n capacitor)
L7805CV 5v regulator (..or pretty much any other 5v regulator)
assortment of wire
a heatsink for the regulator (optional)
old piece of board
Tools--
Soldering Iron
Solder
Pliers

The Schematic
This is what you should build it from.
Test It!
Grab your multimeter and hook the positive up to the positive, and the negative to the ground. Don't forget to set it to VDC at the correct range.
Uses--
I tend to use this for testing and because I had this regulator lying around, but you could hook up a female usb connection to charge up your phone or something (won't work with iPhones or iPod touches without a little modification)
