ABSTRACT:
A constant voltage outputting circuit has a differential amplification circuit having two inputs and an output that is connected to a gate of an output transistor. The output transistor is connected between a power supply voltage and an output terminal and controls an output voltage at the output terminal based on an output of the differential amplification circuit. A voltage division resistor divides the output voltage and applies a divided voltage to one input of the differential amplification circuit, and a reference voltage is applied to the other input thereof. A capacitor connected between the power supply voltage and the gate of the output transistor stabilizes the output voltage when the power supply voltage changes.
