MIC5249 Datasheet (Microchip)

MIC5249, 300mA uCap LDO

The MIC5249 is an efficient, precise 300 mA CMOS voltage regulator with power on reset (POR) delay which can be implemented via an external capacitor.

It offers 1% initial accuracy, extremely low dropout voltage (typically 400 mV @ 300 mA), and low ground current (typically 85 mA) over load.
