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