MIC5233  
High Input Voltage  
Low IQ µCap LDO Regulator  
General Description  
Features  
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.  
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  
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.  
Reverse-battery protection  
Reverse-leakage protection  
Thermal-shutdown and current-limit protection  
IttyBitty® SOT-23-5 and SOT-223-3 packages  
Available in fixed and adjustable output voltage versions,  
the MIC5233 is offered in the IttyBitty® SOT-23-5 and  
SOT223-3 package with a junction temperature range of  
40°C to +125°C.  
Data sheets and support documentation can be found on  
Micrel’s web site at: www.micrel.com.  
Applications  
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
