No. 4807—2/3

°C, V

Notes.

All tests are measured using a constant-voltage supply unless otherwise specified.

Output noise voltage is 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. The noise voltage waveform does not inl-

cude any pulse noise.
