TPS631011 provides an active pull down current(67mA typ) to quickly discharge output when the EN is logic low. With this function, the VOUT is connected to ground through internal circuitry, preventing the output from “floating” or entering into an undetermined state. The output discharge function makes the power on and off sequencing smooth. Pay attention to the output discharge function if use this device in applications such as power multiplexing, because the output discharge circuitry creates a constant current path between the multiplexer output and the ground.
