Hello to everybody,
All the system should work at 3.3V, because that's the power supply voltage for the Atmel Dataflash, also there are so many ICs that uses the voltage, and the battery level is 3.7V (nominal). My question is related with how to "regulate" and supply the MCU with a stable 3.3V from a power source with 3.7V nominal. It will be great if I can still have 3.3V when the battery is near 3.4V.
Does anybody use a LiIon battery to power an AVR or any other MCU at 3.36V?
Thanks very much!
