How can I quickly bring the output voltage of a circuit with an LDO to zero in order to set a power supply sequence for the load IC?

Use an LDO with an auto discharge function to quickly force the output voltage to zero. When the LDO is disabled, the auto discharge function turns on the MOSFET connected between V_OUT and GND to quickly discharge the output capacitor, thereby reducing the output voltage to nearly zero.
