Figure 9: Output voltage noise and ripple measurement test

setup. 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.

rated load current (20 mV/div). Load capacitance: 1µF ceramic

capacitor and 10µF tantalum capacitor. Bandwidth: 20 MHz.
