General Description

The MIC5233 is a 100 mA, 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 multicell

Li-Ion battery systems.

A µCap LDO design, the MIC5233 is stable with either

ceramic or tantalum output capacitors. It only requires

a 2.2 µF output capacitor for stability.

Features of the MIC5233 include enable input, thermal

shutdown, current limit and reverse battery protection,

and reverse leakage protection.

Available in fixed and adjustable output voltage ver-

sions, the MIC5233 is offered in the 5-lead SOT23 and

3-lead SOT223 packages with a junction temperature

range of –40°C to +125°C.
