Supply Voltage/LDO Input:

Connect a 1μF capacitor to GND.

LDO-1 Enable.

DESCRIPTION

LDO-2 Enable.

Reference Bypass Capacitor Pin:

Optionally connect capacitor of value 0.01μF to 1μF between this pin and GND to tune in the

desired noise and PSRR performance.

No Connection

GND is the connection to system ground. Connect to PCB Ground plane.

LDO-2 Output:

Connect capacitor of value 1μF to 10μF to GND (1µF recommended).

LDO-1 Output:

Connect capacitor of value 1μF to 10μF to GND (1µF recommended).
