8.4.1 Shutdown Mode

The EN pin provides electrical ON and OFF control for the LV14360. When VEN is below 1 V, the device is in shutdown mode. The switching regulator is turned off and the quiescent current drops to 1 µA, typically. The LV14360 also employs UVLO protection. If VIN voltage is below the UVLO level, the regulator is turned off.
