(DC output full loading and nominal AC input voltage range)
3.1.6 Ripple and Noise
Total composite ripple and noise less than 320mV for +16V output, and less than 150mV for +5V output, and 50mV for
+3.3V output tested by DC loading side parallel with a 47uF/EC and 0.1uF/Ceramic. Capacitors and measured band-width
with DC-20MHz
3.1.7 DC Output Voltage and Current
Current
DC Output Voltage Typ. Max.
