摘要： It is an object of the present invention to provide an output circuit capable of reducing a consumption current while an output current is suppressed in a case where limitation is placed on an output voltage so as not to fall to a predetermined voltage or less in an output circuit the emitter of which is grounded, the base of which serves as an input node for a control current and the collector of which serves as an output node. Provided are a base current supply section for supplying a base current to the output transistor according to an input signal from the outside, and a base current control section for detecting an inter-terminal voltage between the collector and emitter of the output transistor to control a base current supplied from the base current supply section so as not to cause the inter-terminal voltage to fall to a value lower than a predetermined voltage.
