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