300mA High PSRR, Fast Response Linear Regulator
DESCRIPTION
FEATURES
BL8067 series is a group of positive voltage
output, low power consumption, low dropout
voltage regulator.




BL8067 can provide output value in the range of
1.0V~4.5V every 0.1V step. It also can be
customized on command.





BL8067 includes high accuracy voltage reference,
error amplifier, current limit circuit and output
driver module with discharge capability.


** Vdrop=Vin1-(Vout2*0.98) Vout2 is the output voltage when Vin=Vout1+1.0V and Iout=300mA. Vin1 is the input
voltage at which the output voltage becomes 98% of Vout1 after gradually decreasing the input voltage.
