EPAD
Input voltage pin. A minimum 0.1µF ceramic capacitor is required for proper operation.
Enable pin. High on this pin enables the device.
Ground pin.
In the adjustable output voltage option, this pin is connected to the external feedback resistor divider which sets
the LDO output voltage. In the 3.3V and 5V options, this pin is not used and can be connected to ground.
Regulated output voltage. A 10µF ceramic capacitor is required for stability.
It is recommended to solder the EPAD to the ground plane.
