Build-in chip enable and discharge circuit

Built-in output current limit circuit

The BL8077 is a group of positive voltage output,

low power consumption, low dropout voltage

regulator. The very low power consumption of

BL8077 (0.8uA, Typ) can greatly improve natural

life of batteries. The BL8077 includes high

accuracy voltage reference, error amplifier and

output driver module with discharge capability.

And it also provides foldback short-circuit

protection, thermal protection and output

current limit function.



APPLICATIONS

The BL8077 can provide output value of fixed

version as 1.2V, 1.8V, 2.5V, 2.8V, 3V, and 3.3V. It

also can be customized on command.
