Voltage regulator with improved overshoot and undershoot voltage compensation

A voltage regulator includes an error amplifier; an output transistor; and a first transistor including a gate for inputting a reference voltage and a source for inputting an output voltage. The first transistor is configured to cause a current to flow when the output voltage becomes an irregular vo...

More Information
Summary:A voltage regulator includes an error amplifier; an output transistor; and a first transistor including a gate for inputting a reference voltage and a source for inputting an output voltage. The first transistor is configured to cause a current to flow when the output voltage becomes an irregular voltage, and a current of the output transistor is controlled based on the current flowing through the first transistor. The voltage regulator capable of improving the overshoot or undershoot of the output voltage in a wide temperature range and to reduce a delay in detection of the overshoot or undershoot.
