3 Description

The LP5912-EP is a low-noise, low-dropout regulator (LDO) that can supply up to 500 mA of output current. Designed to meet the requirements of RF and analog circuits, the LP5912-EP provides low noise, high PSRR, low quiescent current, and low line and load transient response. The LP5912-EP offers class-leading noise performance without a noise bypass capacitor and with the ability for remote output capacitance placement.

The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (a separate noise bypass capacitor is not required).

This device is available with fixed output voltages from 0.8 V to 5.5 V in 25-mV steps. Contact the Texas Instruments Sales office for specific voltage option requirements.
