MIC5245  
150mA µCap CMOS LDO Regulator  
Preliminary Information  
General Description  
Features  
The MIC5245 is an efficient, precise CMOS voltage regulator  
optimized for ultra-low-noise applications. The MIC5245 of-  
fers better than 1% initial accuracy, extremely low dropout  
voltage (typically 150mV at 150mA) and constant ground  
current over load (typically 100µA). The MIC5245 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 dropout100mV @ 100mA  
Ultralow noise30µV(rms)  
Stability with tantalum or ceramic capacitors  
Load independent, ultralow ground current  
150mA output current  
Current limiting  
Thermal Shutdown  
Tight load and line regulation  
• “Zerooff-mode current  
Fast transient response  
Designed specifically for hand-held and battery-powered  
devices, the MIC5245 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 MIC5245 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  
tospeedupdeviceturnoff.AvailableintheIttyBittySOT-23-5  
and power MSO-8 packages, the MIC5245 also offers a  
range of fixed output voltages.
