Description for the LP5907

The LP5907 is a low-noise LDO that can supply up to 250 mA output current. Designed tomeet the requirements of RF and analog circuits, the LP5907 device provides low noise, high PSRR,low quiescent current, and low line or load transient response figures. Using new innovative designtechniques, the LP5907 offers class-leading noise performance without a noise bypass capacitor andthe ability for remote output capacitor placement.

The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (noseparate noise bypass capacitor is required).

This device is available with fixed output voltages from 1.2 V to 4.5 V in 25-mV steps.Contact Texas Instruments Sales for specific voltage option needs.
