BL8569

Dual 500mA High PSRR Linear Regulator

DESCRIPTION

FEATURES

•

Two low dropout voltage regulators

500mA output current for each LDO

Low output noise (50uVRMS)

Low dropout Voltage:0.08V@150mA(Typ)

Standby Mode: 0.1uA

High Ripple Rijection:72dB@1000Hz (Typ)

Excellent Line regulation: 0.05%/V

Independent Shutdown controls

1.2V to 4.5V Factory-Preset Output

Output Current Limit

BL8569 dual,low-noise,low-dropout regulator

delivers at least 500mA of continuous output

current. The output voltage for each regulator

is set independently by trimming.Voltages are

selectable in 100mV steps within a range of

1.2V to 4.5V. The BL8569 includes two

independent logic-controlled shutdown inputs

and allows the output of each regulator to be

turned of independently.

BL8569 includes high accuracy voltage

reference, error amplifier, current limit circuit

and output driver module.

Highly Accurate: ±2%
