I want to power a PIC16f877 with the output from an LM7805 at +5v connected to a 9v 800mapower supply. I read on the pic16f877's data sheet that the maximum current that can be applied to Vdd is 250ma. The LM7805 data sheet just says it can deliver 1A. What i want to know is how much current will the LM7805 supply...will it be 800ma from the main supply?, or higher/lower? I just want to know if i will able to connect the output directly to the PIC without having to limit the current. Thanks.
