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.
