Figure 8: Output voltage response to step-change in load
current (75%-50% of Io, max; di/dt = 0.1A/µs). Load cap: 10µF
tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout
(100mV/div, 50us/div), Bottom Trace: Iout (2A/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
