6.3.1 Enable and Disable

Forcing EN/FLT pin low disables the device, which greatly reduces the VINP power consumption. Pull the EN/FLT pin high to enable normal device functionality. The EN/FLT pin has a weak internal pull-down resistor so it is not recommended to leave this pin floating in noisy systems.
