(3) when v in falls below the minimum operating voltage, the out put becomes undefined. in this case the output becomes v in because it is pulled up. (4) v ss is output when v in rises above the minimum operating voltage. the v ss level still appears even when v sense surpasses ? v det , as long as it does not exceed the release voltage + v det . when v sense rises above + v det , the nch transistor becomes off and v in is output. v in at the vdout pin is delayed for t d due to the delay circuit.
