Description

The LP5907 is a linear regulator capable of supplying 250-mA output current. Designed to meet 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 design techniques, the LP5907 offers class-leading noise performance without a noise bypass capacitor and 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 (no bypass capacitor is required).

The device is available in 4-bump ultra-thin DSBGA, 5-pin SOT-23, and 4-pin X2SON packages. This device is available between 1.2 V and 4.5 V in 25-mV steps. Contact Texas Instruments Sales for specific voltage option needs.
