Notes.

For power supply at the time of test, use a constant-voltage power supply

unless otherwise speciﬁed.

*1 For measurement of available time for load short-circuit and output noise

voltage, use the speciﬁed transformer power supply shown right.

*2 The output noise voltage is represented by the peak value on rms scale

(VTVM) of average value indicating type. The noise voltage waveform

includes no ﬂicker noise.
