Automotive 250mA Ultralow-Noise Low-IQ LDO - LP5907-Q1

LP5907-Q1 (ACTIVE)

Automotive 250mA Ultralow-Noise Low-IQ LDO

 

Description

The LP5907-Q1 is a low-noise LDO that can supply 250 mA of output current. Designed to meet the requirements of RF and analog circuits, the LP5907-Q1 device provides low noise, high PSRR, low quiescent current, and low line or load transient response figures. Using new innovative design techniques, the LP5907-Q1 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 separate 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.

For all available packages, see the orderable addendum at the end of the data sheet.
