3.3V to 3V - Power a GameBoy Color from USB Answered
I want to power my GameBoy Color using the USB port. It needs 3V ( 2 AA batteries). I found a voltage regulator, that puts out 3V, but it does not seem to be available in Germany. But there are loads of 3.3V regulators. So I wonder, how I could use one of those. Is it possible to simply put a resistor in row (if yes, what value would be suitable?) or is it a bit more complicated?
