6.4.4 Disabled

The outputs of the device can be shutdown by forcing the voltage of the enable pin to less than VEN(LOW) (minimum); see the Electrical Characteristics table.

The device is disabled if VIN < VIN(min) (4V).

When disabled, the pass transistor is turned off and internal circuits are shutdown.
