a simple variable power supply circuit
This variable power supply circuit utilizes the L200 integrated circuit, which is designed for adjustable voltage regulation. The L200 can provide a stable output voltage that can be finely tuned using a 10K potentiometer, allowing for a versatile range of applications. The output voltage can be adjusted between approximately 3V and 15V, making it suitable for powering various electronic devices that require different voltage levels.
The circuit operates by connecting the L200's output to the load, with the voltage adjustment achieved through the variable resistor. The potentiometer alters the feedback voltage to the L200, effectively changing the output voltage according to the user's requirements. The current output capability of the circuit ranges from a minimum of 10 mA to a maximum of 2 A, ensuring that it can handle a variety of loads without overheating or becoming unstable.
In terms of design, it is important to include appropriate filtering capacitors on both the input and output sides of the L200 to ensure stable operation and minimize voltage ripple. Additionally, heat dissipation should be considered, as the L200 can generate heat under load. A suitable heat sink may be required to maintain safe operating temperatures.
This variable power supply circuit is ideal for laboratory use, prototyping, and other applications where adjustable voltage and current are necessary. The simplicity of the design, combined with the flexibility of the L200 IC, makes it a valuable tool for engineers and hobbyists alike.Variable power supply based L200 for its output voltage is controlled by a variable resistor 10K. Output voltage range of values is from around 3 to 15 volts, and current range is about 10 mA minimum and a maximum of 2 amps.
