This is a simple yet reliable device based on one of the oldest integrated voltage regulators, the LM723.

The LM723 is a versatile voltage regulator that can be configured to provide a wide range of output voltages. It is capable of delivering a maximum output current of 3A, making it suitable for various applications, including power supplies and voltage regulation circuits. The device operates over a wide input voltage range, typically from 4.5V to 40V, and can be adjusted to provide output voltages from 1.25V to 37V.

The LM723 features several key components that enhance its functionality. It includes an internal voltage reference, which ensures stable output voltage, and a feedback loop that regulates the output based on the load conditions. The regulator can be used in both linear and switching power supply designs, which allows for flexibility in circuit design.

In terms of pin configuration, the LM723 consists of several pins, including an input pin for the supply voltage, an output pin for the regulated voltage, and adjustment pins for setting the output voltage level. Additionally, it has a ground pin that is crucial for establishing a common reference point in the circuit.

For thermal management, the LM723 can be equipped with a heat sink to dissipate excess heat generated during operation, especially when handling higher currents. This is essential to maintain the reliability and longevity of the device.

Overall, the LM723 remains a popular choice in electronic design due to its robustness, ease of use, and adaptability across various applications. Its long-standing presence in the market underscores its reliability and effectiveness as a voltage regulation solution.This is a simple but reliable device based one of the oldest integrated voltage regulators of them all - the LM723.. 🔗 External reference
