General Description

The MIC5233 is a 100mA highly accurate, low dropout

regulator with high input voltage and ultra-low ground current.

This combination 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 shut-

down, current limit, reverse battery protection, and

reverse leakage protection.

Available in fixed and adjustable output voltage versions, the

MIC5233 is offered in the IttyBitty™ SOT-23-5 package with

a junction temperature range of –40°C to +125°C.
