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).
