BL8068

700mA High PSRR, Low Noise, Fast Response Linear Regulator

DESCRIPTION

BL8068 series is a group of positive voltage output,

low power consumption, low dropout voltage

regulator.

BL8068 can provide output value in the range of

1.2V~4.5V every 0.1V step. It also can be customized

on command.

BL8068 includes high accuracy voltage reference,

error ampliﬁer, current limit circuit and output driver

module with discharge capability.

BL8068 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%.

BL8068 is available in SOT-23-5, SC-70-5 packages

which is lead free.
