Abstract
PURPOSE: To obtain a DC stabilizing power source which can control a large amount of the load power via the transistor featuring a small amount of power consumption, by connecting the resistance in parallel to the control transistor.
CONSTITUTION: The DC voltage of non-stabilizing power source 1 is supplied to load 4 via transistor Q1 which resistance R1 is connected in parallel with control given by control circuit 2. Transistor Q1 is turned on and off when the output voltage of power source 1 is high and low respectively, and is also controlled at the intermediate level of the output voltage so that the current may be branched off to Q1 and R1 each. The control via Q1 becomes impossible when the load current is small, and accordingly the apparent load current to transistor Q1 is increased for transistor Q2 which is controlled by control circuit 3. Thus the stabilization is secured for the voltage to load 4.
