MIC5233-5.0BM5集成电路（IC）的线性+开关稳压器规格书PDF中文资料

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 and SOT223-3 package with a junction temperature range of −40°C to +125°C.
