Output voltage ripple at nominal input voltage and rated load
current (Io=3A) (50 mV/div, 5us/div). Load capacitance: 1µF ceramic
capacitor and 10µF tantalum capacitor. Bandwidth: 20 MHz. Scope
measurements should be made using a BNC cable (length shorter than 20
inches). Position the load between 51 mm to 76 mm (2 inches to 3 inches)
from the module
