MIC5225
Ultra-Low Quiescent Current
150mA μCap Low Dropout Regulator
General Description
Features
The MIC5225 is a 150mA 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 MIC5225 ideal for a wide variety of
applications including USB and portable electronics
applications, using 1-cell, 2-cell or 3-cell Li-Ion battery
inputs.
A μCap LDO design, the MIC5225 is stable with either a
ceramic or tantalum output capacitor. It only requires a
2.2μF capacitor for stability.
Features of the MIC5225 includes enable input, thermal
shutdown, current limit, reverse battery protection, and
reverse leakage protection.
Available in fixed and adjustable output voltage versions,
the MIC5225 is offered in the IttyBitty ? SOT23-5 package
