IC 723 TIP41 Laboratory Power Supply Variable voltage

A person visiting the website is interested in a DC voltage adjustable regulator that can output between 1.2V to 12V with a current capacity of 1-2A. Initially, the individual considers using the LM317 integrated circuit for this purpose. However, they mention having multiple LM723 ICs available. The discussion revolves around which circuit would be better, with a preference for a simpler design that utilizes the specified integrated circuit. Additionally, the circuit incorporates transistors such as the TIP41 or TIP31 to enhance the current output to approximately 1-2A. A variable resistor (VR1) is included to allow for voltage adjustment as desired.

The proposed adjustable DC voltage regulator circuit employs the LM317 integrated circuit, known for its versatility and ease of use in various applications. The LM317 can provide an output voltage adjustable from 1.25V to 37V, making it suitable for the specified range of 1.2V to 12V. The circuit typically includes a few external resistors to set the output voltage, as well as a capacitor for stability.

In this design, the LM723 can also be utilized as an alternative to the LM317. The LM723 is a more robust voltage regulator capable of delivering higher currents and operating at higher input voltages. It features built-in current limiting and thermal shutdown, which enhances the safety and reliability of the circuit.

To achieve the desired current output of 1-2A, power transistors such as the TIP41 or TIP31 are incorporated into the circuit. These transistors act as pass elements, allowing the regulator to handle higher currents than the LM317 or LM723 can manage on their own. The transistors are connected in a configuration that enables them to amplify the current output while maintaining the adjustable voltage characteristic.

The variable resistor (VR1) serves as a means to fine-tune the output voltage according to user requirements. By adjusting the resistance value, the feedback voltage to the LM317 or LM723 can be modified, resulting in a change in the output voltage. This feature is particularly useful in applications where precise voltage control is necessary.

Overall, this adjustable DC voltage regulator circuit is designed for ease of assembly and operation, making it suitable for a variety of electronic projects where adjustable voltage and current are needed. The combination of the LM317 or LM723 with power transistors ensures that the circuit can deliver stable performance across the specified voltage and current ranges, while the inclusion of a variable resistor allows for user-defined adjustments.Person see the website wants DC Volt adjustable Regulate 1. 2V to 12V current 1-2A sizes at the first stage me think will choose the circuit that use IC LM317. But he tells have IC LM723 the many. Then of this circuit better which this easy circuit, use integrated number this circuit. And still use number transistor TIP41 0R TIP31 help enlarge curr ent get about 1-2A fine VR1 for choose Volt follow want.
