Supply Voltage/LDO Input:
Connect a 1µF capacitor to GND.
LDO-1 Enable.
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.
POR2 Delay Setting Capacitor Pin:
Connect a capacitor between this pin and GND to delay the POR2 output release after LDO-2
output reaches 94% of its specified voltage level. (200ms delay per 0.01µF).
GND is the connection to system ground. Connect to PCB Ground plane.
Internally connected to VO1 through 100kΩ resistor.
Internally connected to VO2 through 100kΩ resistor.
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).
