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  
provides 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. Anoise bypass pin is also available for  
further reduction of output noise.  
• Input voltage range: 2.7V to 6.0V  
• PSRR = 50dB @ V + 0.3V  
O
• 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  
• “Zero” off-mode current  
Designed specifically for handheld and battery-powered  
devices, the MIC5252 provides a TTL-logic-compatible en-  
able pin. When disabled, power consumption drops nearly  
to zero.  
• 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  
• Cellular phones and pagers  
• Cellular accessories  
• Battery-powered equipment  
• Laptop, notebook, and palmtop computers  
• Consumer/personal electronics  
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.
