发明名称 Regulator
摘要 A regulator includes a first transistor, a first bias circuit, a second bias circuit, a differential circuit having second to fifth transistors, and a current mirror circuit. The first transistor outputs an output voltage lower than the input voltage. The first bias circuit generates a first bias voltage lower than a reference voltage. The second bias circuit generates a second bias voltage lower than a feedback voltage relating to the output voltage. The second transistor into which the reference voltage is inputted and the third transistor into which the feedback voltage is inputted are a pair of differential transistors. The fourth transistor is complementarily connected to the second transistor. The fifth transistor is complementarily connected to the third transistor. The differential circuit outputs a comparison signal to the first transistor. The current mirror circuit is connected to the second and third transistors.
