(1) 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 can turn off until the input voltage rises above 7 V.
(2) This test is done with VOUT in regulation, measuring the VIN – VOUT parameter when VOUT drops by 100 mV from the programmed value (of VOUT) at specified loads.
(3) Specified by design - not tested.
(4) Design Information - not tested; specified by characterization.
