ELECTRICAL CHARACTERISTICS
Notes:
1 . Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.
2 . S h o r t C i r c u i t p r o t e c t i o n i s o n l y a s s u r e d u p t o V
3 . I f n o t t e s t e d , s h a l l b e g u a r a n t e e d t o t h e s p e c i f i e d l i m i t s .
Changes in output voltage due to heating effects must be taken into account separately.
The • denotes the specifications which apply over the full operating temperature range.
