3V Voltage Regulator with Shutdown Feature

mackrackit,

I'm sure there has to be a way to control this shutdown pin with circuitry without holding a pushbutton. Thanks anyways for your idea.

I misunderstood,
you want the pic or some circuit to start the rgulator?
I was thinking you were just going to have the pic do the shut down.

mackrackit,

Well, yes I want the pic to do the shutdown.

OK then,the suggestion I made before was how to start it.

To have the PIC control it have a PIN with a pull down resistor that is connected to the enable pin of the regulator. Said PIN will always be HIGH until the program makes it low for what ever reason you code it for.

mackrackit,

Yeah, but I don't want to start the circuit with a pushbutton. I have already designed my circuit and it does not use a pushbutton to start it. It uses a slide switch and I want to keep it like that for some other design reasons. Anyways, I will keep your idea in mind for future projects.
