    Default Re: Minimize battery consumption on a 18F2550

    Will this schematic work?

    When u press a button the FET will switch on the 7805 and the PIC, and then I hold RA4 low as long I want the PIC to run.
    The +BATT terminal is from a 9V battery and the datasheet says that RA4 can handle up to 14 volts if I have understand it right, so 9V on RA4 will be OK?
