LM317 Adjustable Voltage Power Supply Board Learning Kit

An LM317 Adjustable Voltage Power Supply Board Learning Kit is a DIY electronics kit that uses the LM317 voltage regulator to create a variable DC power supply, allowing users to adjust the output voltage (typically from 1.25V to 12V) and providing features like overload and thermal protection. These kits are ideal for beginners and students to learn about voltage regulation and provide a practical power source for various electronic projects and experiments, often including additional tools like a buzzer or signal generator. 

Features

• Adjustable Output Voltage: The primary feature is the continuously adjustable DC output voltage, typically ranging from 1.25V to 12V, set by a potentiometer.
  
• LM317 Voltage Regulator: The core component is the LM317 integrated circuit (IC), a positive-voltage regulator.
  
• Protection Features: The LM317 provides built-in current limiting, thermal overload protection, and safe operating area protection to prevent damage to the circuit.
  
• DIY & Educational: The kit requires self-assembly through soldering, making it an excellent tool for electronics hobbyists and students to learn about circuit building and practical applications of voltage regulation.
  
• Compact & Portable: Many kits come with an acrylic case or a compact PCB for a durable and functional power supply.
  
• Low Output Current: The typical output current for these kits is around 200mA, suitable for lower-power applications.
  
• Optional Features: Some kits include additional features like a built-in buzzer for wire testing or a signal generator for creating low-frequency pulse signals.
