Ground.
Output Voltage Pin. The output voltage follows the input voltage. When EN is low or
VIN is UVLO, the output voltage is discharged by an internal resistor.
Power Supply Input Connect this pin to external DC supply.
Pulling the ENB above 2V or EN below 0.8V will disable the device, and pulling ENB
pin below 0.8V or EN above 2V will enable the device.
The EN and ENB pins cannot be left floating.
Not Connected Internally.
