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.
