Hi,
I would like to use a CR2032 3V battery for a project that I am doing. It will be powering an atmega 328p microcontroller (which accepts 1.8-5.5v). I am thinking of using a Low Dropout Regulator (LDO) to ensure that it doesn't go above 3V to protect the IC, but what do I do when battery voltage of the battery goes below 3v casuing the LDO to outputting current? (or below the droput voltage for that matter?). I pretty much want a 3V (or 2.7?) regulated power supply to the IC.
Any suggestions would be appreciated!
Thanks!
