MIC5233 Datasheet | Micrel Semiconductor

Micrel High Input Voltage, Low IQ µCap LDO Regulator General Description The MIC5233 is a 100m A highly accurate, low dropout regulator with high input voltage and ultra-low ground current. This bination of high voltage and low ground current makes the MIC5233 ideal for multi-cell Li-Ion battery systems. A µCap LDO design, the MIC5233 is stable with either ceramic or tantalum output capacitor. It only requires a 2.2µF capacitor for stability. Features of the MIC5233 include enable input, thermal shutdown, current limit, reverse battery protection, and reverse leakage protection. Available in fixed and adjustable output voltage versions, the MIC5233 is offered in the Itty Bitty™ SOT-23-5 package with a junction temperature range of - 40°C to +125°C.
