Abstract
A voltage regulator has an error amplifier circuit, and a phase compensation circuit having a capacitor connected in parallel to first and second series-connected resistors. A control transistor has its source-drain path connected between input and output terminals of the phase compensation circuit and its gate connected to a junction point between the first and second resistors. In a transient stage in which the output voltage of the error amplifier circuit changes, the resistance of the phase compensation circuit decreases thereby improving the transient response characteristics of the voltage regulator.
