Übersicht
Description
The LM317AEMP is equipped with features such as current limiting, thermal overload protection, and safe area compensation, which enhance its durability and operational safety. It requires only two external resistors to set the output voltage, simplifying circuit design and implementation. The device is typically packaged in a TO-220, TO-263, or SOT-223 package, which allows for efficient heat dissipation.
Overall, the LM317AEMP is a popular choice for powering digital and analog circuits, providing a regulated output with minimal external components. It is ideal for applications in consumer electronics, industrial equipment, and other areas requiring efficient voltage regulation.
Features
1. Adjustable Output Voltage: It allows for output voltages ranging from 1.25V to 37V, making it suitable for a wide range of applications.
2. Output Current: Capable of delivering output currents up to 1.5A, depending on the input-output voltage differential.
3. Line Regulation: Provides excellent line regulation, typically 0.01%/V, which ensures stable performance even with varying input voltages.
4. Load Regulation: Offers load regulation of 0.1%, providing consistent output voltage despite changes in load current.
5. Thermal Overload Protection: Includes built-in protection against overheating, enhancing the reliability and longevity of the device.
6. Short-Circuit Protection: Equipped with current limiting features to protect against short-circuits.
7. Safe Operating Area Protection: Ensures the device operates safely within its specified limits.
8. Low Dropout Voltage: Features a dropout voltage of around 3V at maximum load, optimizing performance in low-voltage applications.
9. Package Options: Available in a variety of packaging options, including TO-220, TO-263, and SOT-223, to suit different application needs.
This combination of features makes the LM317AEMP a popular choice for power supply design and voltage regulation in electronic projects.
Package
Pinout
1. Input (IN): This pin is where the unregulated voltage is applied.
2. Output (OUT): This pin provides the regulated output voltage. It is adjustable from 1.25V to 37V with the help of two external resistors.
3. Adjustment (ADJ): This pin is used to set the output voltage. By connecting resistors between the OUT and ADJ pins and from ADJ to ground, the output voltage can be precisely adjusted.
The LM317AEMP is designed for positive voltage regulation and is capable of delivering output currents in excess of 1.5A. Its compact, surface-mount package makes it suitable for various electronic devices and applications where space is a constraint.
