Figure 8: Output voltage response to step-change in load
current (75%-50%-75% of Io, max; di/dt = 0.1A/µs). Load cap:
10µF tantalum capacitor and 1µF ceramic capacitor. Top Trace:
Vout (50mV/div, 200us/div), Bottom Trace: Iout (5A/div). 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
