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