I have pictured is what I believe to be an LDO voltage regulator(?) I've been using google to help identify this part as much as possible. The package size seems to be SOT-23 thin. It has 162C printed on the top (my pic does not show it completely). I'm looking at replacements on digikey, but need advice (guidance), if possible, for a substitute. Measurements I've taken from a working board: the input voltage is around 7.2v (battery pack voltage) and the output is 3.3v. Thank you!
