Notes

1. BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40°C. MIL-HDBK-217F Notice2 @Ta=25 °C, Full load(Ground, Benign, controlled environment).

2. Maximum value at nominal input and full load.

3. Typical value at nominal input and no load.

4. Typical value at nominal input and full load.

5. Test by minimum input and constant resistive load.

6. The output requires minimum loading on the ou tput to maintain specified regulation. Operation under no-load condition will not damage these devices, however, they may not meet all listed specification.

7. Single output installs a potentiome ter to adjust the output voltage.

8. Load regulation for dual output: Min load to 100% load balanced on all outputs.

9. Cross regulation for dual output: asymmetrical load 25% / 100% FL

10. The ON/OF F voltage is referenced to -INPUT To order negative logic ON/OFF control add the suffix -N.
