For input voltages higher than 30 Vdc, a 22 µF / 50 V input capacitor is required. 2. Tested at nominal input, 20~100% load for 3.3 Vdc model, 20 MHz bandwidth, with 10 µF electrolytic and 1 µF ceramic capacitor on the output. At loads below 10%, the max ripple and noise of the 3.3 & 5 Vdc outputs will be 150 mVp-p, and the other outputs will be 2% Vo. 3. Measured at min Vin, full load. 4. All specifications are measured at Ta=25°C, humidity < 75%, nominal input voltage, and rated output load unless otherwise specified.

To reduce the output ripple furtherly, it is suggested to connect a “LC” filter at the output terminal, and recommended value of L is 10µH-47µH.
