Circuit has a constant voltage adapted to maintain a stable feature output independently of the changes of a voltage source

摘要

A circuit has a constant voltage, in particular includes a transistor of control of the output q3 is connected between a voltage source and a ground potential, and a divider circuit r1, r2, d2, d3, which is connected between the sender of the transistor and the ground potential. The sender of the transistor appearance of a voltage predetermined at the output of divider which corresponds in addition to the output terminal of the circuit has a constant voltage. The transistor is connected to a is not formed on the effect of modulation of the width of the base under the effect of variations of the input voltage, which fact that its potential of 10 remains constant.
