Small Variable Power Supply
The LM723 voltage regulator is a versatile and widely used component in electronic circuits, providing adjustable output voltage and current regulation. It operates over a voltage range of 1.3 to 12.2 volts and can supply a maximum output current of 1 ampere. The device is known for its robust performance and reliability, making it suitable for various applications, including power supplies, battery chargers, and voltage stabilization circuits.
The LM723 features over-current protection, which is crucial for safeguarding both the regulator and the connected load from excessive current conditions. This protection is typically implemented using an external resistor and a transistor in the feedback loop, which monitors the output current and limits it to a safe value.
In a typical application circuit, the LM723 is connected with a few external components: two resistors are used to set the desired output voltage, while capacitors may be included for stability and noise filtering. An input capacitor is often recommended to smooth out fluctuations in the input voltage, and an output capacitor helps stabilize the output voltage and improve transient response.
The device can be configured for both linear and switching power supply applications, but it is primarily used in linear configurations due to its simplicity and ease of implementation. The LM723's ability to maintain a stable output voltage despite variations in input voltage and load conditions makes it an essential component in the design of reliable electronic power supply systems.
Overall, the LM723 voltage regulator remains a popular choice for engineers and designers seeking a dependable solution for voltage regulation in various electronic applications.Features: 1.3-12.2 V, 1 A, over-current protection. This is a simple but reliable device based one of the oldest integrated voltage regulators of them all - the LM723. 🔗 External reference
