Note 16:
Reverse current is higher for the case of (rated_output) < VOUT combinations of input voltage and output current. Limit the output current < VIN, because the no-load recovery circuitry is active in this region and is range if operating at maximum input voltage. Limit the input-to-output trying to restore the output voltage to its nominal value. voltage differential range if operating at maximum output current.
