Notes:

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.

2

. Short Circuit protection is only assured up to V

3

. If not tested, shall be guaranteed to the specified limits.

The • denotes the specifications which apply over the full operating temperature range.
