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

* Cin is required if regulator is located more than
4 inches from power supply filter. A 1 µF solid
tantalum or 10 µF aluminum electrolytic is
recommended.
** Co is necessary for stability. A 1 µF solid
tantalum or 10 µF aluminum electrolytic is
recommended.
