MIC5246  
150mA µCap CMOS LDO Regulator  
Preliminary Information  
General Description  
Features  
The MIC5246 is an efficient, precise CMOS voltage regulator  
optimized for low-noise applications. The MIC5246 offers  
better than 1% initial accuracy, extremely-low-dropout volt-  
age (typically 150mV at 150mA) and constant ground current  
(typically 85µA)over load . The MIC5246 features an error  
flagthatindicatesanoutputfaultconditionsuchasovercurrent,  
thermalshutdownanddropout.TheMIC5246providesavery  
low noise output, ideal for RF applications where quiet  
voltage sources are required.

Thermal Shutdown  
Tight load and line regulation  
• “Zerooff-mode current  
Stability with low-ESR capacitors  
Fast transient response  
Designed specifically for hand-held and battery-powered  
devices, the MIC5246 provides a TTL-logic-compatible en-  
able pin. When disabled, power consumption drops nearly to  
zero.  
TTL-Logic-controlled enable input  
Applications  
Cellular phones and pagers  
Cellular accessories  
Battery-powered equipment  
The MIC5246 also works with low-ESR ceramic capacitors,  
reducing the amount of board space necessary for power  
applications, critical in hand-held wireless devices.  
Laptop, notebook, and palmtop computers  
PCMCIA V and V regulation/switching  
Key features include current limit, thermal shutdown, a push-  
pull output for faster transient response, and an active clamp  
tospeedupdeviceturnoff.AvailableintheIttyBittySOT-23-5  
package, the MIC5246 also offers a range of fixed output  
voltages.
