REV1.0-Revised DEC 2007

500mA High PSRR, Low Dropout Voltage Linear Regulator

DESCRIPTION

FEATURES

•

Low Power Consumption: 20uA（Typ.）

Low output noise (47uVRMS)

Low dropout Voltage: 0.16V@300mA

(Typ.)

BL8565 series is a group of positive voltage

output, low noise,low power consumption, low

dropout voltage regulator.

BL8565 can provide output value in the range

of 1.5V~4.5V every 0.1V step. It also can be

customized on command.

•

High Ripple Rejection: 73dB@100Hz

(Typ.)

Low

100ppm/°C

Excellent Line regulation: 0.05%/V

Temperature

Coefficient:

BL8565 includes high accuracy voltage

reference, error amplifier, current limit circuit

and output driver module with discharge

capability.

•

Build-in chip enable and discharge circuit

Output Voltage Range: 1.5V~4.5V

(customized on command every 0.1V

step)

Highly Accurate: ±2%

Output Current Limit

BL8565 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%.
