Try the terms "voltage regulator" and "dc converter" on digikey.com. I don't know your constraints, but if you have both a -12v input and a +12v input, you can use three voltage regulators and a few caps to do it. There is probably an IC to do what you want (and probably more efficiently) but they can be hard to sort through and sometimes the circuit configuration is a bit complex. A few voltage regulators is a quick and easy solution.

I mean, I'm not even sure where to start looking for. -- Adam Sulmicki http://www.eax.com The Supreme Headquarters of the 32 bit registers
