You'll need to supply a LOT more information than that to get a specific answer.
Like what current?, what efficiency can you live with?, is noise performance important?, what PCB space can you afford? etc
Dave.
And whether you need ON/OFF control of the regulator so you don't run down your 12V battery.

Look for a dual output buck regulator from the usual suspects : Analog, Linear, National, TI, Maxim. They do exist.
