So. I have a small lipo battery, its voltage goes from 4.2v fully charged and keeps going down i dunno how far, past 1v.
I want to have ~3v for a bunch of LED's, so i figure a 3.3v voltage regulator would work best for what i need.
but i was looking around online and they all have a 'Primary Input Voltage' see
here. Since my battery dosnt supply a constant voltage, can the input voltage be lower or higher than that value? whats the minimum voltage it needs to operate properly?
or would there be an even better option than a voltage regulator that i don't know about?
