Functional Description

Stabilized Power Supply Function

The stabilized power supply includes the following features:

• Wide range of operating input voltage from 6 V to 40 V to provide stabilized voltages

• Availability of any output current, by simply replacing the external transistor

• Fine adjustment of output voltage

Figure 1 shows the fine adjustment circuit of the output circuit. Select the resistor R1 as shown in

equation 1.

Add a resistor between GND and Voadj to increase the output voltage.
