PRODUCTION DATA.
These devices have a high-voltage-tolerant EN pin that an external microcontroller or a digital control circuit can use to enable and disable them. A high input to this pin activates the device and turns the regulator on. For self bias applications, connect this input to the VIN terminal. An internal pulldown resistor is connected to this pin, and therefore if this pin remains unconnected, the device stays disabled.
