(1)

At the lowest input voltage, the loading is less 15%(75mA), the R&N will be 150mVp-p (max.).

2.

(2)

The efficiency is test by max./ min. input voltage and full load @25℃.

3.

(3)

The capacitive load is test by minimum input and constant resistive load.

4.

All specifications valid at nominal input voltage, full load and 25℃ after warm-up time unless otherwise stated.
