MIC5239  
Low Quiescent Current 500mA µCap LDO Regulator  
Advance Information  
General Description  
Features  
The MIC5239 is a low quiescent current, µCap low-dropout  
regulator. With a maximum operating input voltage of 30V  
andaquiescentcurrentof23µA, itisidealforsupplyingkeep-  
alive power in systems with high-voltage batteries.  
• Ultra-low quiescent current (I = 23µA @I = 100µA)  
• Continuious 500mA output current  
• Wide input range: 2.3V to 30V  
• Low dropout voltage:

350mV @500mA;  
±1.0% initial output accuracy  
• Stable with ceramic or tantalum output capacitor  
• Logic compatible enable input  
• Low output voltage error flag indicator  
• Overcurrent protection  
Capable of 500mA output, the MIC5239 has a dropout  
voltage of only 350mV. It can provide high output current for  
applications such as USB.  
As a µCap LDO, the MIC5239 is stable with either a ceramic  
or a tantalum output capacitor. It only requires a 3.3µF output  
capacitor for stability.  
• Thermal shutdown  
TheMIC5239includesalogiccompatibleenableinputandan  
undervoltage error flag indicator. Other features of the  
MIC5239 include thermal shutdown, current-limit, overvolt-  
age shutdown, load-dump protection, reverse leakage pro-  
tections, and reverse battery protection.  
• Reverse-leakage protection  
• Reverse-battery protection  
• High-power SOIC-8, MSOP-8 and SOT-223 packages  
Applications  
• USB power supply  
• Keep-alive supply in notebook and portable personal  
computers  
Available in the thermally enhanced SOIC-8, MSOP-8 and  
SOT-223, the MIC5239 comes in fixed 3.0V and adjustable  
voltages. For other output voltages, contact Micrel.  
• Logic supply from high-voltage batteries  
• Automotive electronics  
• Battery-powered systems
