Vue d'ensemble
Description
The device is equipped with internal current limiting, thermal overload protection, and safe area compensation, making it robust against over-current and overheating scenarios. It requires only two external resistors to set the output voltage, offering flexibility and simplicity in design. Additionally, the LM317MADTRKG can be used in a variety of applications, including power supplies, battery chargers, and LED drivers.
Manufactured by ON Semiconductor, it is available in a TO-252 surface-mount package, providing a compact solution suitable for modern, space-constrained circuit boards. Its broad input voltage range, precise regulation, and protective features make it a popular choice among engineers and hobbyists for both simple and complex electronic projects.
Features
1. Adjustable Output Voltage: It can provide an output voltage range from 1.25V to 37V, which you can set using two external resistors.
2. Output Current: It supports an output current of up to 500 mA.
3. Line Regulation: Typically, the line regulation is around 0.01% per volt, ensuring minimal output voltage changes with input voltage fluctuations.
4. Load Regulation: It offers a load regulation of about 0.1%, which helps maintain a stable output voltage despite changes in load current.
5. Thermal Protection: The LM317 includes built-in thermal overload protection to prevent damage due to excessive temperature.
6. Current Limiting: It features current limiting to protect against overcurrent conditions.
7. Package Type: It is available in a surface-mount package (DPAK), which is suitable for compact and space-constrained applications.
These features make the LM317MADTRKG a reliable choice for a variety of applications, including power supplies, battery chargers, and embedded systems.
Package
Pinout
1. Input Pin: This pin receives the input voltage that needs to be regulated. It should be higher than the desired output voltage by a certain margin to ensure proper regulation.
2. Output Pin: The regulated output voltage is taken from this pin. The voltage level can be adjusted by varying the resistance connected between the output and adjust pins.
3. Adjust Pin: This pin is used to set the output voltage. By connecting external resistors between the adjust pin and the output pin, the output voltage can be finely tuned as per the requirements.
The LM317MADTRKG is commonly used in power supply circuits to provide a stable and adjustable output voltage.
