LDO Output: Output of voltage regulator. Place capacitor to ground to bypass the output

voltage. Nominal bypass capacitor is 10µF.

LDO Input: Connect to SW output. Requires a bypass capacitor to ground. Nominal

bypass capacitor is 10µF.

Input Supply Voltage (Input): Requires bypass capacitor to GND. Nominal bypass

capacitor is 10µF.

Enable (Input): Logic low will shut down the device, reducing the quiescent current to less

than 50µA. This pin can also be used as an undervoltage lockout function by connecting a

resistor divider from EN/UVLO pin to VIN and GND. It should be not left open.

Power Ground.
