Abstract
The voltage regulator includes a reference voltage circuit configured to feed back the reference voltage as a feedback voltage and to output the reference voltage, a soft-start circuit configured to output a control signal for controlling the reference voltage to rise linearly at a start of power supply, a voltage divider circuit configured to output a divided voltage, an error amplifier circuit configured to amplify and output a difference between the reference voltage and the divided voltage, and an output transistor controlled by an output voltage of the error amplifier circuit. The reference voltage circuit includes an analog switch transistor having a gate controlled by the control signal, and the feedback voltage is an output voltage from the analog switch transistor.
