PRODUCTION DATA
The ON/OFF pin for the device is an active-high pin. The output voltage is enabled when the voltage of the ON/OFF pin is greater than the high-level input voltage of the ON/OFF pin and disabled when the ON/OFF pin voltage is less than the low-level input voltage of the ON/OFF pin. If independent control of the output voltage is not needed, connect the ON/OFF pin to the input of the device.
For the new chip, the device has an internal pulldown circuit that activates when the device is disabled by pulling the ON/OFF pin voltage lower than the low-level input voltage of the ON/OFF pin to actively discharge the output voltage.
