The purpose of the output discharge function is to ensure a defined ramp-down of the output voltage when the device is disabled.
The internal discharge resistor is connected to the VOS pin. The discharge function is enabled as soon as the device is disabled or if UVLO is entered. It is not active during Thermal Shutdown. The discharge circuit remains active as long as the input voltage is above 0.7 V.
