S-87X Series

Transient Response
An undershoot or an overshoot may occur in the output voltage of the voltage regulator if input voltage or load current fluctuates
transiently. If an undershoot is large, the voltage detector operates to output reset signal in the S-87XXXXB Series in which the
voltage detector detects the output voltage of the regulator. If an overshoot is large, the load circuit is adversely affected.
Therefore it is important to determine the capacitor value so as to minimize undershoot and overshoot.
1. Line Transient Response due to Input Voltage Ffluctuation
Input voltage fluctuation differs depending on the types of the signal applied: type
Ι
which is a rectangular wave between
(V
OUT
+ 1) V and 10 V, and type
ΙΙ
which is a rectangular wave from 0 V to 10 V (see Figure 16). The ringing waveforms and
parameter dependency of each type are described below. The measuring circuit is shown in Figure 17 for reference, .
