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 provides 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 specically for handheld and battery-powered  
devices, the MIC5255 provides a TTL-logic-compatible en-  
able pin. When disabled, power consumption drops nearly  
to zero.  
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
