LR8563

Low noise, fast response 300mA LDO regulato

General Description

Features

• ^{Low Power Consumption: 15uA（Typ.）}

• ^{Low Output Noise (47uVRMS)}

• ^{Standby Mode: 0.1uA}

LR8563 series is a group of positive

voltage output, low power consumption,

low dropout voltage regulator.

LR8563 can provide output value in the

range of 1.5V~4.5V every 0.1V step. It also

can be customized on command.

• ^{Low Dropout Voltage0.16V@300mA}

(Typ.)

• ^{High Ripple Rejection: 73dB@100Hz}

(Typ.)

LR8563 includes high accuracy voltage

reference, error amplifier, current limit

circuit and output driver module with

discharge capability.

• ^{Low Temperature Coefficient: ±}

100ppm/°C

• ^{Excellent Line Regulation: 0.05%/V}

LR8563 has excellent load and line

transient response and good temperature

characteristics, which can assure the

stability of chip and power system. And it

uses trimming technique to guarantee

output voltage accuracy within±2%.

• ^{Build-in Chip Enable And Discharge}

Circuit

• ^{Output Voltage Range: 1.5V~4.5V}

(customized on command every 0.1V step)

• ^{Highly Accurate: ±2% (±1%}

customized)

LR8563 is available in SOT-23-5, SC-70-5

packages which is lead free. It also can

available in these packages with lead.

• ^{Output Current Limit}

Applications：

• ^{Power source for cellular phones and}

various kind of PCSs

• ^{Battery Powered equipment}

• ^{Power Management of MP3, PDA, DSC,}
