LP5910 300-mA Low-Noise, Low-I_QLDO

1 Features

3 Description

•

Input voltage range: 1.3 V to 3.3 V

Output voltage range: 0.8 V to 2.3 V

Output current: 300 mA

The LP5910 is a low-noise LDO that can supply

up to 300 mA of output current. Designed to meet

the requirements of RF and analog circuits, this

device provides low noise, high PSRR, low quiescent

current, and superior line transient and load transient

response. Using new innovative design techniques

the LP5910 offers class-leading noise performance

without a noise bypass capacitor and with the option

for remote output capacitor placement.

PSRR: 75 dB at 1 kHz

Output voltage tolerance: ±2%

Low dropout: 120 mV (typical)

Very low I_Q(enabled, no load): 12 µA

Low output-voltage noise: 12 µV_RMS

Stable with ceramic input and output capacitors

Thermal overload protection

Short-circuit protection

Reverse current protection

Automatic output discharge for fast turnoff

The device contains a reverse current protection

circuit that prevents a reverse current flow through the

LDO to the IN pin when the input voltage is lower than

the output voltage.

2 Applications

When the Enable (EN) pin is low, and the output is

in an OFF state, an automatic output discharge circuit

discharges the output capacitance for fast turnoff.

•

Mobile phones and tablets

Digital cameras and audio devices

Portable and battery-powered equipment

Portable medical equipment

Virtual reality

With its low input and low output voltage range the

LP5910 is well-suited as a post DC-DC regulator

(post BUCK regulator) or for single- or dual-cell

applications.

RF, PLL, VCO, and clock power supplies

IP cameras

The device is designed to work with a 1-μF input and

a 1-μF output ceramic capacitor. A separate noise

bypass capacitor is not required.

This device is available with fixed output voltages

from 0.8 V to 2.3 V in 25-mV steps. Contact Texas

Instruments Sales for specific voltage option needs.
