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