MIC5247  
150mA Low-Voltage µCap Linear Regulator  
Preliminary Information  
General Description  
Features  
The MIC5247 is an efficient, precise low voltage CMOS  
voltage regulator optimized for ultra-low-noise applications.  
TheMIC5247offersbetterthan1%initialaccuracy,and85µA  
constant ground current over load (typically 85µA). The  
MIC5247 provides a very low noise output, ideal for RF  
applications where quiet voltage sources are required. A  
noise bypass pin is also available for further reduction of  
output noise.  
Ultralow noise  
Low voltage outputs  
Load independent, ultralow ground current: 85µA  
150mA output current  
Current limiting  
Thermal Shutdown  
Tight load and line regulation  
• “Zerooff-mode current  
Stability with low-ESR capacitors  
Fast transient response  
Logic-controlled enable input  
Designed specifically for hand-held and battery-powered  
devices,theMIC5247providesalogiccompatibleenablepin.  
When disabled, power consumption drops nearly to zero.  
Applications  
Cellular phones and pagers  
Cellular accessories  
The MIC5247 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in hand-held wireless devices.  
Key features include current limit, thermal shutdown, a push-  
pull output for faster transient response, and an active clamp
