Abstract
A voltage regulator has an output transistor that outputs an output voltage. A first circuit controls a control terminal voltage to increase the output voltage when an undershoot has occurred in the output voltage. A second circuit controls the control terminal voltage to prevent an output current from exceeding an overcurrent when the output current becomes the overcurrent, and disables the first circuit when the output current is prevented from exceeding the overcurrent so that the first circuit does not control the control terminal voltage to increase the output voltage.
