Variable PSU
The variable power supply circuit utilizing the L200 voltage regulator is designed to deliver adjustable voltage and current outputs, making it suitable for a variety of electronic applications. The L200 is a versatile integrated circuit that allows for easy configuration to achieve desired output levels.
The circuit typically consists of the L200 regulator, several resistors, capacitors, and diodes, which work together to stabilize and adjust the output voltage and current. The output voltage can be set by selecting appropriate resistor values connected to the feedback pin of the L200, while the output current can be limited by configuring a current sensing resistor in the circuit.
To implement the circuit, the L200 requires a power supply input that is higher than the desired output voltage. This input voltage is connected to the regulator's input pin. The output pin of the L200 provides the adjustable voltage, which can range from a few volts up to a maximum specified by the datasheet. A potentiometer may be used in conjunction with fixed resistors to allow for fine-tuning of the output voltage.
In addition, capacitors placed at the input and output of the regulator help filter noise and stabilize the voltage levels. A heat sink may be necessary for the L200 to dissipate heat generated during operation, especially when high current levels are drawn.
Safety features such as overcurrent protection can also be included by integrating additional components, ensuring that the circuit operates reliably under varying load conditions. Overall, the L200-based variable power supply circuit is an effective solution for providing adjustable power in laboratory setups, testing environments, and various electronic projects.A variable power supply with adjustable voltage and current outputs made with the L200 regulator.
