Figure 14: Output voltage ripple at nominal input voltage and rated load current (Io=4A)(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.
