Abstract
Provided is a voltage regulator capable of stably suppressing overshoot. The voltage regulator includes a non-regulated state detection circuit for detecting a non-regulated state, and an overshoot suppression circuit. The overshoot suppression circuit is configured to operate when the non-regulated state detection circuit detects the non-regulated state.
Claims3
A voltage regulator, comprising:
- a first differential amplifier circuit for comparing a feedback voltage obtained by dividing an output voltage of an output terminal and a first reference voltage to each other to control an output transistor,
- an overshoot suppression circuit for suppressing overshoot of the output voltage;
- and
- a non-regulated state detection circuit for detecting a non-regulated state based on a gate voltage of the output transistor,
- wherein the overshoot suppression circuit suppresses the overshoot of the output voltage when the non-regulated state detection circuit detects the non-regulated state to detect the overshoot.
