(20 mA/div, 20us/div).
Figure 15: Output voltage ripple at nominal input voltage and
rated load current (50 mV/div, 2us/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.
