MIC5235  
Ultra-Low Quiescent Current, 150mA  
µCap LDO Regulator  
General Description  
Features  
The MIC5235 is a 150mA 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 MIC5235 ideal for USB and portable  
electronics applications, using 1-cell, 2-cell or 3-cell Li-Ion  
battery inputs.  
Wide input voltage range: 2.3V to 24V  
Ultra low ground current: 18µA  
Low dropout voltage: 310mV at 150mA  
High output accuracy: ±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  
Adjustable output from 1.24V-20V  
A µCap LDO design, the MIC5235 is stable with either  
ceramic or tantalum output capacitor. It only requires a  
2.2µF capacitor for stability.  
Features of the MIC5235 includes enable input, thermal  
shutdown, current limit, reverse battery protection, and  
reverse leakage protection.  
Available in fixed and adjustable output voltage versions,  
the MIC5235 is offered in the IttyBitty® SOT-23-5 package  
with a junction temperature range of –40°C to +125°C.  
Applications  
USB power supply  
Cellular phones  
Keep-alive supply in notebook and portable computers  
Logic supply for high-voltage batteries  
Automotive electronics  
Battery powered systems
