Dan,
You can use an LM7805 which is a standard 5 volt regulator. Good for 1 amp
(but at 1 amp it will need a heatsink and it will get hot - especially when
driven from 12 volts). With the device laying on the table with the legs
toward you, from left to right the 3 pins are Input, Ground, and Output (the
tab on the top is ground also). Put about a 1000 MFD cap between output and
ground (+ to the output) if you want to pull the full amp - smaller cap if you
are pulling less current or if your input is clean (like a DC source - in which
case about 100 mfd is probably plenty). Part is available from RS as well as
www.mouser.com and digi-key.
Thanks,
Jim W

Hi
If I remember correctly, there was a Radio Shack Part Number for a 12VDC to
5VDC converter posted recently.

It's amazing what you can do if you don't know it can't be done.
