The LM317AT is a popular adjustable voltage regulator with a 3-pin configuration. Its primary function is to provide a stable output voltage that can be adjusted over a range of approximately 1.25V to 37V, with a maximum output current of 1.5A. The three pins are configured as follows:
1. Input (IN): This pin receives the unregulated input voltage that the LM317AT will regulate. It should be connected to a voltage source higher than the desired output voltage.
2. Output (OUT): This pin provides the regulated output voltage. The voltage level is set using external resistors connected to the adjust pin.
3. Adjust (ADJ): The adjust pin is used to set the output voltage. By connecting a resistor between this pin and the output ground, and another resistor between the output and adjust pins, the output voltage can be precisely controlled.
The LM317AT is commonly used in power supply circuits, offering features like thermal overload protection and short-circuit protection to ensure reliable operation.
