I am considering using an LM1117T 3.3 regulator to supply an ATtiny85.
The only micro function is to drive a 12 VDC output (via a N channel MOSFET).
The project power supply is a 12 VDC battery to supply both the Tiny85 as well as
the 12 VDC output.
The current project is using a 7805 to supply the Tiny85 with 5 VDC VCC.
It works fine but I wish to extend the battery life if I can.
Question: Will using the 3.3 vs. the 5 VDC regulator offer any power savings ?
Note: I am already using a sleep mode and a wakeup on WDT interrupt.
I am thinking that perhaps driving the Tiny85 with 3.3 volts will increase some battery life ?
