LP5907

SNVS798O –APRIL 2012–REVISED JUNE 2020

LP5907 250-mA, Ultra-Low-Noise, Low-I_QLDO

1 Features

3 Description

The LP5907 is a low-noise LDO that can supply up to

•

Input voltage range: 2.2 V to 5.5 V

Output voltage range: 1.2 V to 4.5 V

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.

Stable with 1-µF ceramic input and output

capacitors

•

No noise bypass capacitor required

Remote output capacitor placement

Thermal-overload and short-circuit protection

–40°C to 125°C operating junction temperature

Low output voltage noise: < 6.5 µV_RMS

PSRR: 82 dB at 1 kHz

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).

Output voltage tolerance: ±2%

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.

Very low I_Q(enabled): 12 µA

Low dropout: 120 mV (typical)
