    Hi,

    I'm trying to hunt down a regulator that can produce a regulated +/- 12V supply from a 12V battery pack. Ideally I'd like it to have an enable/shutdown pin that can be controlled via a uprocessor and reduce the quiescent current to a few uAs or less. Does anyone have any suggestions? I've been searching for a few hours and can't seem to find one with the necessary specs.

    Thanks!

    An important information is missing: what's the max current for the negative supply?

    I could recommend a switched capacitor voltage inverter IC like the LT1054 but you can't draw too much current from it.
