otherwise noted. Typical values are at T
Note 1: This is the time from an output overcurrent or short-circuit condition until the output goes into regulated current limit.
Note 2: OUT voltage above which the output current limit is at its full value.
Note 3: See the Overcurrent Protection section.
Note 4: This is the time the part stays in current-limit mode during overload condition. After t
