Note. All tests are measured 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. Specified Transformer Supply (RP-25 or Equivalent)
