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.

* 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.
