Enable (EN)

The LP5907 EN pin is internally held low by a 1-MΩ resistor to GND. The EN pin voltage must be higher than the VIH threshold to ensure that the device is fully enabled under all operating conditions. The EN pin voltage must be lower than the VIL threshold to ensure that the device is fully disabled and the automatic output discharge is activated.
