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.
