Abstract

PURPOSE: To prevent oscillation, maintaining a high controlling property, by inserting the voltage drop means between the collector of the amplifying transistor and the base of the controlling transistor.
CONSTITUTION: When the voltage E0 between the output terminals 1, 2 is varied, a collector current of the detection transistor 5 is varied, a collector current of the amplifying transistor 12 is also varied, by which the base potential of the controlling transistor 14 is varied, and the output voltage E0 is controlled so that it is returned to its original value. It is prevented to cause high frequency oscillation, by inserting the voltage drop means consisting of diodes 21, 22, between the collector of the amplifying transistor 12 and the base of the controlling transistor 14.
