8.4.2 Standby Mode

Start-up and shutdown are controlled by the EN input. This input features precision thresholds, allowing the use of an external voltage divider to provide an adjustable input UVLO. Applying a voltage of ≥ 1.14 causes the device to enter standby mode, powering the internal LDO, but not producing an output voltage. Increasing the EN voltage to 1.231 V (typ.) fully enables the device, allowing it to enter start-up mode and starting the soft-start period. When the EN input is brought below 1.121 V (110-mV hysteresis), the regulator stops running and enters standby mode. Further decrease in the EN voltage to below 0.3 V completely shuts down the device.
