What is an output discharge function of the load switch IC?

The output discharge function brings the VOUT voltage to the GND level when the output of a load switch IC is disabled. When the load switch IC is disabled, the  output discharge function turns on the internal MOSFET between VOUT and GND, quickly discharging the capacitor connected to the VOUT terminal. This function is necessary for the proper operation of advanced electronic systems requiring exact power sequencing for various circuits, microprocessor units (MPUs), and other ICs.
