MIC5249 Datasheet (Micrel Semiconductor)

MIC5249, 300mA uCap LDO

The MIC5249 is an efficient, precise 300mA 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 400mV @ 300mA), and low ground current (typically 85mA) over load.

MIC5249 Features

* of the MIC5249 include a logic-compatible enable pin, current limit, thermal shutdown, ultra-fast transient response, and an active clamp to speed up device turnoff. The MIC5249 also works with low-ESR ceramic capacitors, reducing the amount of board space necessary for power applications, critical
