MIC5233 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 Cap LDO design, the MIC5233 is stable with either ceramic or tantalum output capacitor. It only requires a 2.2F 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 IttyBitty™ SOT-23-5 package with a junction temperature range of 40°C to +125°C.
