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
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.
