SNVSA34E September 2014 – December 2019 LP5907-Q1
The LP5907-Q1 Enable (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.
When the EN pin is pulled low, and the output is disabled, the output automatic discharge circuitry is activated. Any charge on the OUT pin is discharged to GND through the internal 230-Ω (typical) pull-down resistance.
