Thread: Auto-off circuit?

I am looking for a circuit that I can implement that will allow a pic to
turn itself off. I have tried going into sleep mode after a timer time-out,
but the battery drain is still too much.

I would like to power up using a momentary push button switch.

By the way, in sleep mode, my 16f8xx is drawing over 1mA, even after
following the suggested procedures to minimize drain.

I want to power the pic from a 9volt transistor radio battery. I am using a
78L05 regulator. Are there any regulators that have a shut down option?

Thanks

John
