BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at 40ºC.

MIL-HDBK-217F Notice2 @Ta=25 ºC, Full load(Ground, Benign, controlled environment).

Maximum value at nominal input voltage and full load.

Typical value at nominal input voltage and full load.

Test by minimum Vin and constant resistive load.

The output requires a minimum loading on the output to maintain specified regulation. Operation under no-load condition will not

damage these devices, however they may not meet all listed specification.
