MIC5253  
100mA Low Noise µCap Teeny™ LDO  
General Description  
Features  
The MIC5253 is an efficient, CMOS voltage regulator opti-  
mized for ultra-low-noise applications. It offers 1.5% initial  
accuracy, extremely low dropout voltage (165mV at 100mA),  
and low ground current (typically 95µA at full load). The  
MIC5253 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 5.5V  
TeenySC-70-5 package  
Ultra-low output noise: 30µV(rms)  
100mA continuous output current, 150mA peak current  
Stability with ceramic output capacitors  
Ultralow dropout: 165mV @ 100mA  
High output accuracy:  
1.5% initial accuracy  
3.0% over temperature  
Low ground current: 95µA  
TTL-Logic-controlled enable input

Thermal shutdown and current limit protection  
Designed specifically for handheld and battery-powered de-  
vices, the MIC5253 provides a TTL-logic-compatible enable  
pin.Whendisabled,powerconsumptiondropsnearlytozero.  
The MIC5253 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  
Available in the Teeny™ SC-70-5 package, the MIC5253  
offers a wide range of output voltages. Key features include  
current limit, thermal shutdown, faster transient response,  
and an active clamp to speed up device turn-off.
