Circuit 64:
Stabilizer for 1.9 V
Setup information
Install the three transistors and the four resistors as shown in
Fig. 2.64
. Next come the eleven jumper wires.
Check the placement on the board again and only then connect the battery.

1 x 2N3906 transistor,
2 x 2N3904 transistors,
1 x 3.3 k
Ω
resistor,
1 x 2.2 k
Ω
resistor, 2 x 1 k
Ω
resistors, 1 x breadboard,
1 x 9V battery with clip
connector

Stabilizer for 1.9 V
Experiment
By means of this circuit, a small, regulated output voltage is generated. The 1 k
Ω
resistor serves as load. You
can check the output voltage using a multimeter. In our Circuit we measured approximately 1.9V.
The circuit diagram for this experiment is shown in Chap. 3, Fig. 3.64.
