2. Load and line regulation are specified at constant junction temperature. Changes in V O due to heating effects must be taken into account separately.
3. C Adj , when used, is connected between the adjustment pin and ground.
4. Since Long–Term Stability cannot be measured on each device before shipment, this specification is an engineering estimate of average stability
5. Thermal Resistance evaluated measuring the hottest temperature on the die using an infrared scanner. This method of evaluation yields very
6. The average die temperature is used to derive the value of thermal resistance junction to case (average).
Pulse testing with low duty cycle is used.
