VIN can go down to 4 V for 130 ms or less and remain functional. If VIN is less than 7 V for longer than 130 ms, then some devices may turn off until the input voltage rises above 7 V.
This test is done with VOUT in regulation and VIN – VOUT parameter is measured when VOUT (3.3 V or 5 V) drops by 100 mV at specified loads.
