Note.
All tests are made using a constant-voltage supply unless otherwise specified.
Available time for load short-circuit and output noise voltage are measured using the transformer supply specified below.
The output noise voltage is the peak value of an average-reading meter with an rms value scale (VTVM). A regulated AC
supply (50Hz) should be used to eliminate the effects of AC primary line flicker noise.
