voltage of the regulator. In the product types in which the output voltage of the regulator is detected by the
detector, if the output voltage is the detection voltage or lower due to the undershoot, the detector operates
and a reset signal may be output. To prevent this, set the value of the input-and-output capacitor of a
regulator so that the undershoot is the minimum value or set a voltage range that allows the difference
between the output voltage and detection voltage to be equal to or greater than the undershoot.
