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. 2. If not tested, shall be guaranteed to the specified limits. 3. The • denotes the specifications which apply over the full operating temperature range.
