Hi,

I've got a small PIC project with a 7805 regulator.

The project works ok if I connect 5V from an external source.

Thanks for your help guys. I've re-read my programmer manual and
apparently it is able to steal power from the circuit being programmed. I
assume that is to prevent exactly this situation.

I'll replace the reg and be a bit more careful next time.

Thanks

Michael
