MIC5235-3.3YM5-TR

MIC5235-3.3YM5-TR 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 device ideal for USB and portable electronics applications, using 1-cell, 2-cell, or 3-cell Li-Ion battery inputs. As a µCap LDO design, the MIC5235 is stable with either a ceramic or tantalum output capacitor. It only requires a 2.2μF capacitor for stability. Features of the MIC5235 include enabling input, thermal shutdown, current limit, reverse battery protection, and reverse leakage protection. Application includes USB power supply, cellular phones, keep-alive supply in a notebook and portable computers, logic supply for high-voltage batteries, automotive electronics, and battery-powered systems.
