MIC5233

MIC5233 Micrel MIC5233 High Input Voltage, Low IQ µCap LDO Regulator 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 package with a junction temperature range of –40°C to +125°C. Features Wide input voltage range: 2.3V to 36V Ultra low ground current: 18µA Low dropout voltage of 270mV at 100mA High output accuracy of ±2.0% over temperature µCap: stable with ceramic or tantalum capacitors Excellent line and load regulation specifications Zero shutdown current Reverse battery protection Reverse leakage protection Thermal shutdown and current limit protection IttyBitty™ SOT-23-5 package Keep-alive supply in notebook and portable computers USB power supply Logic supply for high-voltage batteries Automotive electronics Battery powered systems 3-4 cell Li-Ion battery input range Applications Ordering Information Part Number MIC5233-1.8BM5 MIC5233-2.5BM5 MIC5...
