MIC5239  
Low Quiescent Current 500mA  
µCap LDO Regulator  
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)

• Continuous 500mA output current  
• Wide input range: 2.3V to 30V  
• Low dropout voltage:  
350mV @500mA  
Capable of 500mA output, the MIC5239 has a dropout  
voltage of only 350mV. It can provide high output current for  
applications such as USB.  
±1.0% initial output accuracy  
• Stable with ceramic or tantalum output capacitor  
• Logic compatible enable input  
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.  
• Low output voltage error flag indicator  
• Overcurrent protection  
• Thermal shutdown  
TheMIC5239includesalogiccompatibleenableinputandan  
undervoltage error flag indicator. Other features of the  
MIC5239 include thermal shutdown, current limit, overvolt-  
age shutdown, reverse-leakage protection, and reverse-  
battery protection.  
• Reverse-leakage protection  
• Reverse-battery protection  
• High-power SOIC-8, MSOP-8 and SOT-223 packages  
Applications  
Available in the thermally enhanced SOIC-8, MSOP-8 and  
SOT-223, the MIC5239 comes in fixed 1.5V, 1.8V, 2.5V,  
3.0V, 3.3V and 5.0V, and adjustable voltages. For other  
output voltages, contact Micrel.  
• USB power supply  
• Keep-alive supply in notebook and portable personal  
computers  
• Logic supply from high voltage batteries  
• Automotive electronics
