Notes.

All tests are made using a constant-voltage supply unless otherwise specified.

1. Available time for load short-circuit and output noise voltage are measured using the transformer supply specified

below.

2. The output noise voltage is the peak value of an average-reading meter with an rms value scale. The noise voltage

waveform does not inlcude any pulse noise.
