The MIC5205-1.8 is a pin-compatible alternative in the same SOT-23-5 footprint with a fixed 1.8V output. However, the dropout and quiescent current specs differ — verify the MIC5205-1.8 dropout at your load current and its Iq against your power budget before treating them as drop-in equivalents. The MAX8878EUK18-T carries reverse polarity protection that the MIC5205 does not, which may matter in field-serviceable equipment.
