I'm a little stuck with 5V power supply selection for a PIC that can draw between a few uA sleeping to 75mA peak (RS485, Relay, XBee etc...) with an average draw of 0.5-2mA
I would like it to generate as little heat as possible, considering the following

- 3xAA batteries maybe but prefer external mains power
