Let's see...5 volts @ 10 amps...50 watts! Can anything be that important in a custom circuit board? Your are not going to find something simple to get you from 12 volts to 5 volts @10 amps. The biggest three terminal voltage regulator is only capable of a three or four amps, the standard 7805 is only an amp and a half. To get 5 volts regulated from the 12 volt supply you have to dump something like 70 watts into heat just to make the conversion. You can use the 7805 to drive a couple of power transistors in parallel but you would get 5.6 volts output.
