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 (100mV/div, 200us/div),
Bottom Trace: Iout (20A/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
