LP5951 - 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.

Key Features

  • internal protection against shortcircuit currents and over-temperature conditions. Performance is specified for a -40˚C to 125˚C 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. Features n n n n n n n n n n n n n Excellent line transient response: ± 2mV typ. Excellent PSRR: -60dB at 1kHz.
