Supply Voltage/LDO Input:

Connect a 1µF capacitor to GND.

LDO-1 Enable.

DESCRIPTION

LDO-2 Enable.

Reference Bypass Capacitor Pin:

Optionally connect capacitor with a value of 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 with a value of 1µF to 10µF to GND (1µF recommended).

LDO-1 Output:

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