At full load, nominal input, 20 MHz bandwidth oscilloscope, with a 0.33 F ceramic capacitor on the output. 2. Required to add a 2.2 F (5 & 12 Vdc input models) or 4.7 F (24 Vdc input models) ceramic capacitor to the input to reduce input voltage stress. 3. All specifications are measured at Ta=25C, nominal input voltage, and rated output load unless otherwise specified.
