I'm currently powering a PIC12F629 with 4 AA batteries. The 629 is rated at 6.5 V max, so I'm within specs. However the internal oscillator is not accurate at 6V - I have to place a resistor on VDD or VSS or the frequency is off so much it causes communication errors.
So I thought I would do things right and properly regulate the voltage at 5V. However after looking at the 7805 datasheet I see the minimum input voltage is 8V.
Now, since the thing does work properly at 6V (batteries) with a resistor, do I even need a regulator? If so, what should I use to produce 5V from 6V?
