Microchip Technology, Inc. High Vin, Low Iq LDO Regulator MIC5233

The MIC5233 is a 100mA, highly accurate, low dropout regulator with high input voltage and ultra-low ground current. This combination of high input 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 capacitors. 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. Additional Features AEC-Q100 Qualified and PPAP Capable 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 off-mode current Reverse battery protection Reverse leakage protection Thermal shutdown and current limit protection IttyBitty® SOT-23-5 package
