SNVS345F –JUNE 2006–REVISED MAY 2013

LP5951 Micropower, 150mA Low-Dropout CMOS Voltage Regulator

Check for Samples: LP5951

FEATURES

DESCRIPTION

The LP5951 regulator is designed to meet the

requirements of portable, battery-powered systems

•

Excellent Line Transient Response: ±2mV typ.

Excellent PSRR: -60dB at 1kHz typ.

Low Quiescent Current of 29µA typ.

1.8 to 5.5V Input Voltage Range

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.

Small SC70-5 and SOT-23-5 Packages

Fast Turn-on Time of 30µs typ.

The LP5951 is designed to be stable with small 1µF

ceramic capacitors.

Typ. < 1nA Quiescent Current in Shutdown

Ensured 150mA Output Current

The LP5951 also features internal protection against

short-circuit

conditions.

currents

and

over-temperature

Output Voltage Range: 1.3V to 3.7V

Logic Controlled Enable 0.4V/0.9V

Performance is specified for a -40°C to 125°C

temperature range.

Good Load Transient Response of 50mVpp

typ.

The device is available in SOT-23-5 and SC70-5

package.

•

Thermal-overload and Short-circuit Protection

-40°C to +125°C Junction Temperature Range

The device is available in fixed output voltages in the

range of 1.3V to 3.7V. For availability, please contact
