ンジスタＴ２はこの制御にはほとんど寄与しない。The circuit device described above has the following adjusting function. For example,
As the operating voltage U B for the voltage regulator increases, a larger current I S flows through the resistors R1, R2, R3 of the voltage divider. This causes a larger voltage drop across the resistor R2, which controls the first transistor T1 to be conductive. As a result, the collector current of the transistor T1 flows and the emitter-collector voltage of the transistor T1—which corresponds to the base-emitter voltage of the transistor T2—decreases. Therefore, the collector current of the transistor T2 decreases. The collector current of T1 and the collector current of T2 are added, and they flow to the ground via the reference element and the resistor R3. This added current is
It has a larger value than the current flowing through E and R3 before the conduction of T1. This is because the circuit element is designed so that the collector current of T1 becomes larger than the collector current decrease amount of T2. In the limit state, T2
The collector current of T1 has a minimum value of zero, while the collector current of T1 further increases. The voltage drop across R3 is higher due to the increased current flowing through R3. This increases the positive potential. Therefore terminals 13 and 1
The voltage available from 4 remains sufficiently stable when the circuit arrangement is designed accordingly. The control characteristic of this regulator depends mainly on the action of the transistor T1, and the transistor T2 contributes little to this control.

る電圧供給のために使用することができる。Changes in ambient temperature do not affect the voltage generated by the voltage regulator. Because the transistor T1 and the transistor T2 are complementary transistor pairs,
This is because the emitter voltage U BE changes in the opposite direction when the temperature changes. Suitable complementary transistors are, for example, a transistor pair of the BCW61D type for the transistor T1 and a BCW60D type for the transistor T2, specially constructed for these purposes. As the reference element, MPS5010
The type is advantageous. The resistance value of the resistor R1 is changed to the resistance R2
It is advantageous to make it equal to twice the resistance value of. This voltage regulator can be used to supply a voltage to an integrated driver stage for a liquid crystal display device (LCD display) operating in a multiplexer, if the voltage divider is correspondingly supplemented by another resistor or another tap. it can.
