FUNCTION
Ground.
Power Supply Input. Connect this pin to external DC supply.
Enable Input. Pulling this pin to high will enable the device and pulling this pin to
low will disable device. The EN pin cannot be left floating.
Enable Input. Pulling this pin to high will disable the device and pulling this pin to
low will enable device. The ENB pin cannot be left floating.
Fault Indication Pin. This pin goes low when a current limit or an over-temperature
condition is detected after a 12ms deglitch time.
Output Voltage Pin. The output voltage follows the input voltage. When ENB is
high or EN is low, the output voltage is discharged by an internal resistor.
