For input voltages higher than 30 Vdc, a 22 F / 50 V input capacitor is required. 2. Tested at nominal input, 20 MHz bandwidth, with 10 F electrolytic and 1 F ceramic capacitor on the output. For 1.5~3.3 Vdc output models, tested at 20~100% load. For all other models, tested at 10~100% load. At loads below 20% for 1.5~3.3 Vdc output models, the max ripple and noise will be 100 mVp-p. At loads below 10% for all other models, the max ripple and noise will be 150 mVp-p. 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.
