Abstract

PURPOSE: To obtain the optional low voltage output by giving the voltage division to the stabilized voltage output having the temperature coefficient of zero by the resistance and at the same time obtaining this voltage division output through the operational amplifying circuit.
CONSTITUTION: The circuit which forms stabilized voltage Vr' is constituted by the following component parts: transistor Q2 with the base-emitter voltage of diode- connected transistor Q1 applied to the base and resistance R3 provided to the emitter each; transistor Q3 with the collector voltage of Q2 applied to the base and constant current circuit 2 provided to the collector each; and transistor Q4 which receives application of the collector output of Q3 at the base, supplies the emitter output to the collectors of Q1 and Q2 via resistances R1 and R2, and at the same time obtains stabilized Vr' respectively. Then the voltage division is given to voltage Vr' by resistance R4 and R5, and output voltage Vr can be obtained via voltage folower circuit 1 which is formed with the differential amplifying circuit and fed the output back to the inverse input.
