General Description
The MIC5235 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 MIC5235 ideal for USB and portable
electronics applications, using 1-cell, 2-cell or 3-cell Li-Ion
battery inputs.
A µCap LDO design, the MIC5235 is stable with either
ceramic or tantalum output capacitor. It only requires a
2.2µF capacitor for stability.
Features of the MIC5235 includes enable input, thermal
shutdown, current limit, reverse battery protection, and
reverse leakage protection.
Available in fixed and adjustable output voltage versions,
the MIC5235 is offered in the IttyBitty
with a junction temperature range of –40°C to +125°C.
