600mA High PSRR, Low Dropout Voltage Linear Regulator

REV1.0-Revised DEC 2007

BL8069

DESCRIPTION

BL8069 series is a group of positive voltage

output, low noise,low power consumption, low

dropout voltage regulator.

BL8069 can provide output value in the range

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

customized on command.

BL8069

includes

high

accuracy

voltage

reference, error amplifier, current limit circuit

and output driver module with discharge

capability.

BL8069 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%.

BL8069 is available in SOT-89-3 packages

which is lead free.
