Note 1: Load and line regulation are specified at a constant junction temperature. Pulse testing with low
duty cycle is used. Changes in output voltage due to heating effects must be taken into account separately.
Note 2: Short Circuit protection is only assured up to VIN = 35V
Note 3: If not tested, shall be guaranteed to the specified limits.
The • denotes the specifications which apply over the full operating temperature range. If not noted TA = 25°C
