ELECTRICAL CHARACTERISTICS CURVES
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 100µF ceramic capacitor. Trace: Vout
(200mV/div), Scope measurement should be made using a
BNC cable (length shorter than 20 inches). Position the load
between 51mm to 76mm (2 inches to 3 inches) from the
module.
