Load transient response
The overshoot and undershoot are caused in the output voltage if the output current fluctuates while the input
voltage is costant. Figure 9 shows the output voltage fluctuation due to output current change between 10mA and
1 A in square wave. Table 20 shows the parameter dependency when output current fluctuates. For reference,
Figure 10 describes the measuring circuit.

For example, V
= 2 V means the difference
between 6 V and 8 V.
