7.4.1 Shutdown Mode

The EN/UVLO pin provides electrical on and off control of the device. When the EN/UVLO pin voltage is below 0.4 V, the internal LDO is disabled and there is no switching of the internal power MOSFETs. In shutdown mode, the quiescent current drops to 0.55 µA (typical) when VIN is 13.5 V.
