Load transient response based on output current fluctuation
The overshoot and undershoot are caused in the output voltage if the output current fluctuates between 10
μ
A and 50 mA
(between 10
μ
A and 30 mA at the V
RO
pin) while the input voltage is costant. Figure 14 shows the output voltage fluctuation due
to change of output current. Figure 15 shows the measuring circuit for reference. The latter half of this section describes ringing
waveform and parameter dependency.
Output current fluctuation causes ringing. Figure 18 shows the ringing waveform at the V
OUT
pin and Figure 19 shows that
waveform at the V
RO
pin.
