MIC5252  
150mA High PSRR, Low Noise µCap CMOS LDO  
General Description  
Features  
The MIC5252 is an efficient, precise CMOS voltage regulator  
optimized for ultra-low-noise applications. It offers 1% initial  
accuracy, extremely-low dropout voltage (135mV at 150mA)  
and low ground current (typically 90µA). The MIC5252 pro-  
vides a very-low-noise output, ideal for RF applications  
where a clean voltage source is required. The MIC5252 has  
a high PSRR even at low supply voltages, critical for battery  
operated electronics. A noise bypass pin is also available for  
further reduction of output noise.  
Input voltage range: 2.7V to 6.0V  
PSRR = 50dB @ V + 0.3V

Ultra-low output noise: 30µV(rms)  
Stability with ceramic output capacitors  
Ultra-low dropout: 135mV @ 150mA  
High output accuracy:  
1.0% initial accuracy  
2.0% over temperature  
Low quiescent current: 90µA  
Tight load and line regulation  
TTL-Logic-controlled enable input  
• “Zerooff-mode current  
Designed specifically for handheld and battery-powered de-  
vices, the MIC5252 provides a TTL-logic-compatible enable  
pin.Whendisabled,powerconsumptiondropsnearlytozero.  
Thermal shutdown and current limit protection  
The MIC5252 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in handheld wireless devices.  
Applications  
Key features include current limit, thermal shutdown, faster  
transient response, and an active clamp to speed up device  
turn-off. The MIC5252 is available in the 6-pin 2mm × 2mm  
MLF™ package and the IttyBitty® SOT-23-5 package in a  
wide range of output voltages.
