Description for the LP5907-Q1

The LP5907-Q1 is a low-noise LDO that can supply 250 mA of output current. Designed tomeet the requirements of RF and analog circuits, the LP5907-Q1 provides low noise, high PSRR, lowquiescent current, and low line or load transient response figures. Using new innovative designtechniques, the LP5907-Q1 offers class-leading noise performance without a noise bypass capacitorand the 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.
