MIC5157 Overview
Key Specifications
Package: SOIC
Pins: 14
Output Type (varies by manufacturer): Fixed
Max Operating Temp: 85 °C
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 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
