Abstract:
Provided is a voltage regulator having satisfactory transient response characteristics. The voltage regulator includes: a first amplifier for detecting that undershoot occurs in an output voltage; a second amplifier for detecting that overshoot occurs in the output voltage; a first constant current circuit for increasing a bias current of an error amplifier circuit by a first amount for a first time period in response to a signal determined based on one of an output signal of the first amplifier and an output signal of the second amplifier; a second constant current circuit for increasing the bias current of the error amplifier circuit by a second amount larger than the first amount for a second time period shorter than the first time period in response to a signal determined based on the output signal of the first amplifier; and a first switch circuit for pulling up a gate of an output transistor in response to a signal determined based on the output signal of the second amplifier.

Claim (Index 6):
A voltage regulator, comprising:\n an error amplifier circuit for amplifying a difference between a divided voltage obtained by dividing an output voltage output from an output transistor and a reference voltage, and for outputting the amplified difference to control a gate of the output transistor; an undershoot improvement circuit comprising an amplifier for detecting that undershoot occurs in the output voltage,\n the undershoot improvement circuit being configured to operate to improve the undershoot occurring in the output voltage; and \n a first constant current circuit for increasing a bias current of the error amplifier circuit by a first amount for a first time period longer than an operating time period of the undershoot improvement circuit in response to a signal determined based on an output signal of the amplifier.
