LP5951  
Micropower, 150mA Low-Dropout CMOS Voltage  
Regulator  
General Description  
Features  
n Excellent line transient response: 2mV typ.  
n Excellent PSRR: -60dB at 1kHz typ.  
n Low quiescent current of 29µA typ.  
n 1.8 to 5.5V input voltage range  
n Small SOT23-5 package  
The LP5951 regulator is designed to meet the requirements  
of portable, battery-powered systems providing a regulated  
output voltage and low quiescent current. When switched to  
shutdown mode via a logic signal at the Enable pin, the  
power consumption is reduced to virtually zero.  
The LP5951 is designed to be stable with small 1µF/1.5µF  
ceramic capacitors.  
n Fast turn-on time of 30µs typ.  
<
n Typ. 1nA quiescent current in shutdown  
The LP5951 also features internal protection against short-  
circuit currents and over-temperature conditions.  
n Guaranteed 150mA output current  
n Output voltage range: 1.3V to 3.3V  
Performance is specified for a -40˚C to 125˚C temperature  
range.  
n Logic controlled enable 0.4V/0.9V  
n Good load transient response of 50mVpp typ.  
n Thermal-overload and short-circuit protection  
n -40˚C to +125˚C junction temperature range  
The device is currently available in SOT23-5 package and  
will be available in SC70-5 package soon.  
The device is available in fixed output voltages in the range  
of 1.3V to 3.3V. For availability, please contact your local  
NSC sales office.
