MIC5247  
150mA Low-Voltage µCap Linear Regulator  
General Description  
Features  
The MIC5247 is an efficient and precise, low-voltage CMOS  
voltage regulator optimized for ultra-low noise applications.  
The MIC5247 offers better than 1% initial accuracy and  
85µA 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.  
• Ultra-low noise  
• Low-voltage outputs  
• Load independent, ultra-low ground current: 85µA  
• 150mA output current  
• Current limiting  
• Thermal shutdown  
• Tight load and line regulation  
• “Zero” off-mode current  
• Stability with low-ESR capacitors  
• Fast transient response  
• Logic-controlled enable input  
Designed specifically for handheld and battery-powered de-  
vices, the MIC5247 provides a logic compatible enable pin.  
When disabled, power consumption drops nearly to zero.  
The MIC5247 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  
Key features include current limit, thermal shutdown, a push-  
pull output for faster transient response, and an active clamp  
to speed up device turnoff.Available in the 6-pin 2mm × 2mm
