ELECTRICAL CHARACTERISTICS CURVES
Figure 5: Output voltage response to step-change in load
current (50%-75% of Io, max: di/dt =0.1A/µs). Load cap:1µF
ceramic capacitor and 10uF Tantalum capacitor. Top Trace:
Vout (200mV/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.
