(1) The nominal input voltage should be limited to the output clamp voltage for the selected device option as listed in the Electrical Characteristics section
(2) Guaranteed by design. Not tested at production.
(3) For supply voltages below 6V, it is okay to pull up the EN pin to IN directly. For supply voltages greater than 6V, it is recommended to use an appropriate resistor divider between IN, EN and GND to ensure the voltage at the EN pin is within the specified limits.
