Voltage regulator

摘要

Provided is a voltage regulator having improved overshoot characteristics. In the voltage regulator, a current limiting circuit formed of, for example, a constant current source is provided in series to an output transistor, to thereby limit an output overcurrent. Further, a voltage limiting circuit formed of, for example, a diode is provided to an output terminal, to thereby limit an output voltage.

1. A voltage regulator, comprising:
an error amplifier circuit for amplifying and outputting a difference between a divided voltage obtained by dividing a voltage output from a first terminal of an output transistor and a reference voltage, to thereby control a gate of the output transistor; and a current limiting circuit including a current limiting component directly connected in series to a second terminal of the output transistor, for limiting an output current of the output transistor, the first terminal of the output transistor connected to an output terminal.
