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.
