Foldback current limiting of voltage regulator

[khatus]

The foldback current limiting (sometimes referred to as re-entrant current limiting) is similar to current limiting, but here when the limit is crossed (or in case of a short-circuit that reduces output voltage to zero), the current is foldback to a value less than it would deliver under the normal load condition.

Hello guys, I want to know if the output current of the voltage regulator crosses its maximum output current limit(2.2 A) then what will be the value of the output current after foldback? It is said here less than normal load condition but how much less?

This diagram from old 78xx datasheet shows the foldback behavior.
