I'm stuck between choosing to use either a buck converter or a LDO voltage regulator for my heated glove project. The voltage regulator's function in question will be to power the microcontroller. What I am having trouble deciding on is which is better for low power applications. Low power as in powering a microcontroller that draws only a few uA of current. So in any case, which would be better for my project: a buck converter or a low quiescent LDO? Or does it not matter in this case.
Voltage Regulator: LM2936MPX-5.0/NOPB
Buck Converter: LMR14203XMK/NOPB
