150mA DUAL OUTPUT CMOS LOW NOISE

LOW-DROPOUT VOLTAGE REGULATOR

LR6155

Description

Features

Low Output Noise (27uV_RMS

)

The LR6155 is a dual output, low noise, low-dropout

regulator delivers at least 150mA of continuous

output current. The output voltage for each

regulator is set independently by trimming.

Voltages are selectable in 100mV steps within a

range of 1.3V to 5.0V. Typical output noise is

27uV_RMS, and PSRR is 65dB at 1KHz.

Standby Mode: 0.1uA

150mA output current for each channel

25uA Operating Supply Current per channel

High Ripple Rejection: 65dB@1KHz(Typ.)

Low 130mV dropout at 100mA load

Excellent Line Regulation: 0.05%/V

Built-in chip Enable Circuit

The LR6155 includes two independent

logic-controlled shutdown inputs and allows the

output of each regulator to be turned of

independently.

Independent Shutdown Controls

Output Voltage Range: 1.3V~5.0V

250mA Output Current Limit

Highly Accurate: 2% ( ±1% customized)

The LR6155 includes high accuracy voltage

reference, error amplifier, current limit circuit and

output driver module.

TSOP-6 Package

e declare that the material of product

compliance with RoHS requirements.

The LR6155 has excellent load and line transient

response and good temperature characteristics,

which can assure the stability of chip and power

system and LR6155 uses trimming technique to

guarantee output voltage accuracy within ±2%.
