Figure 13: Output voltage noise and ripple measurement test

setup.

Figure 14: 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 measurement 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.
