LP5951
Micropower, 150mA Low-Dropout CMOS Voltage
Regulator
General Description
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.
The LP5951 also features internal protection against short-
circuit currents and over-temperature conditions.
Performance is specified for a -40C to 125C 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.
