MIC5235 Datasheet | Micrel Semiconductor

Micrel Ultra-Low Quiescent Current, 150m A µCap LDO Regulator General Description The MIC5235 is a 150m A highly accurate, low dropout regulator with high input voltage and ultra-low ground current. This bination 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 Itty Bitty™ SOT-23-5 package with a junction temperature range of - 40°C to +125°C.
