Figure 8: Output voltage response to step-change in load

current (75%-50%-75% of Io, max; di/dt = 0.1

/µs). Load cap:

10µF, tantalum capacitor and 1µF ceramic capacitor. Top Trace:

Vout (100mV/div), Bottom Trace: Iout (10

/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.
