MIC5255  
150mA Low Noise µCap CMOS LDO  
General Description  
Features  
The MIC5255 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 MIC5255 pro-  
vides a very-low-noise output, ideal for RF applications  
where a clean voltage source is required. A noise bypass pin  
is also available for further reduction of output noise.  
• Input voltage range: 2.7V to 6.0V  
• Thin SOT package: 1mm height SOT-23-5  
• 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  
Designed specifically for handheld and battery-powered de-  
vices, the MIC5255 provides a TTL-logic-compatible enable  
pin.Whendisabled,powerconsumptiondropsnearlytozero.  
• Low quiescent current: 90µA  
• Tight load and line regulation  
• TTL-Logic-controlled enable input  
• “Zero” off-mode current  
The MIC5255 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in handheld wireless devices.  
• Thermal shutdown and current limit protection  
Key features include current limit, thermal shutdown, faster  
transient response, and an active clamp to speed up device  
turn-off. Available in the 6-pin 2mm × 2mm MLF™ package,  
the IttyBitty® SOT-23-5 package and the new Thin SOT-23-  
5, which offers the same footprint as the standard IttyBitty®  
SOT-23-5, but only 1mm tall. The MIC5255 offers a range of  
output voltages.  
Applications  
• Cellular phones and pagers  
• Cellular accessories  
• Battery-powered equipment  
• Laptop, notebook, and palmtop computers  
• Consumer/personal electronics
