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.
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.
