Overview
Description
Key features of the LM317AT include thermal overload protection, short-circuit protection, and safe area protection, ensuring robustness against over-temperature and over-current conditions. The device requires only two external resistors to set the output voltage, making it simple to configure for different applications.
The LM317AT is widely used in power supply circuits for its ability to handle moderate power levels and its high regulation performance with a dropout voltage of about 3V. It is available in a TO-220 package, which provides good thermal performance with the option to attach a heatsink for improved heat dissipation. This makes it suitable for use in consumer electronics, industrial equipment, and various DIY electronics projects.
Features
1. Output Voltage Range: Adjustable from 1.25V to 37V.
2. Output Current Capability: Can deliver output currents up to 1.5A.
3. Line Regulation: Typically 0.01% per volt, ensuring stable performance across varying input voltages.
4. Load Regulation: Typically 0.1%, maintaining consistent output with changing loads.
5. Thermal Overload Protection: Safeguards against overheating, enhancing reliability.
6. Short-Circuit Protection: Prevents damage from output shorts by limiting current.
7. Floating Operation: Allows for high-voltage applications beyond the input voltage range.
8. Component Simplicity: Requires only two external resistors for setting the output voltage.
9. Operational Temperature: Suitable for a wide temperature range, ensuring robustness in various environments.
These features make the LM317AT ideal for applications requiring adjustable and reliable voltage regulation, including power supplies and battery chargers.
Package
Pinout
The pin count of the LM317AT is three, with the following functions:
1. Input (IN): This pin receives the input voltage, which must be higher than the desired output voltage. It provides the necessary power for the regulation process.
2. Output (OUT): This pin delivers the regulated output voltage, which can be adjusted using external resistors connected to the ADJ pin.
3. Adjustment (ADJ): This pin is used to set the output voltage. By connecting a resistor network between the OUT and ADJ pins, you can adjust the LM317's output voltage based on the desired application.
The LM317AT is popular in various applications due to its ease of use, reliability, and wide operating voltage range.
