Abstract

PURPOSE: To provide a voltage and current output circuit for outputting by automatically switching the voltage and the current in accordance with load, and having a common output terminal and unnecessary for disposing a voltage conversion resistance.
CONSTITUTION: To the output terminal of the regulator REG, an error amplifier for voltage V, a current error amplifer I, and a load detection amplifier L are connected. The voltage error amplifier V generates the control signal corresponding to the difference between the output voltage and the reference value, the current error amplifier I generates the control signal corresponding to the difference between the output current and the reference value. The load detection amplifier L generates the control signal corresponding to the load connected to the output terminal. Either one of the control signals of the voltage error amplifier V and the current error amplifier I is made superior to the other by the predominating means S in accordance with the control signal of the load detection amplifier L and given to REG. REG controls the current or voltage fed by the power source in accordance with the control singal and feeds to the load.
