MIC5157 - Super LDO Regulator Controller

Download the MIC5157 datasheet PDF. This datasheet also covers the MIC5156 variant, as both devices belong to the same super ldo regulator controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The MIC5156, MIC5157, and MIC5158 Super Low-Dropout (LDO) Regulator Controllers are single IC solutions for highcurrent low-dropout linear voltage regulation.

Super LDO™ Regulators have the advantages of an external N-channel power MOSFET as the linear pass element.

Key Features

  • a dropout voltage as low as the RDS(ON) of the external power MOSFET multiplied by the output current. The output current can be as high as the largest MOSFETs can provide. The MIC5156/7/8 family operates from 3V to 36V. The MIC5156 requires an external gate drive supply to provide the higher voltage needed to drive the gate of the external MOSFET. The MIC5157 and MIC5158 each have an internal charge pump tripler to produce the gate drive voltage. The tripler is capable of providing enough volta.
