MIC5233-1.8YM5-TR Microchip

MIC5233 High Input Voltage, Low I Cap LDO Regulator Q Features General Description AEC-Q100 Qualified and PPAP Capable The MIC5233 is a 100 mA, highly accurate, low dropout Available for 5-Lead SOT23 Package Only regulator with high input voltage and ultra-low ground current. This combination of high voltage and low Wide Input Voltage Range: 2.3V to 36V ground current makes the MIC5233 ideal for multicell Ultra-Low Ground Current: 18 A Li-Ion battery systems. Low Dropout Voltage of 270 mV at 100 mA A Cap LDO design, the MIC5233 is stable with either High Output Accuracy of 2.0% Overtemperature ceramic or tantalum output capacitors. It only requires Cap: Stable with Ceramic or Tantalum a 2.2 F output capacitor for stability. Capacitors Features of the MIC5233 include enable input, thermal Excellent Line and Load Regulation Specifications shutdown, current limit and reverse battery protection, Near Zero Shutdown Current: Typical 0.1 A and reverse leakage protection. Reverse Battery Protection Available in fixed and adjustable output voltage ver- Reverse Leakage Protection sions, the MIC5233 is offered in the 5-lead SOT23 and Thermal Shutdown and Current Limit Protection 3-lead SOT223 packages with a junction temperature 5-Lead SOT23 and 3-Lead SOT223 Packages range of 40C to +125C.
