Smart Enable

The enable pin for the device is an active-high pin. The output voltage is enabled when the voltage of the enable pin is greater than the high-level input voltage of the EN pin and disabled with the enable pin voltage is less than the low-level input voltage of the EN pin. If independent control of the output voltage is not needed, connect the enable pin to the input of the device.

This device has a smart enable circuit to reduce quiescent current. When the voltage on the enable pin is driven above VEN(HI), as listed in the Electrical Characteristics table, the device is enabled and the smart enable internal pulldown resistor (REN(PULLDOWN)) is disconnected. When the enable pin is floating, the REN(PULLDOWN) is connected and pulls the enable pin low to disable the device. The REN(PULLDOWN) value is listed in the Electrical Characteristics table.

This device has an internal pulldown circuit that activates when the device is disabled to actively discharge the output voltage.
