The LM317T-DG is a three-pin adjustable voltage regulator. Its primary function is to provide a stable output voltage that can be adjusted over a range of approximately 1.25V to 37V, with an output current capability of up to 1.5A.
The pin configuration is as follows:
1. Input (Vin): This pin is where the unregulated input voltage is supplied. It should be higher than the desired output voltage by at least 3V to ensure proper regulation.
2. Output (Vout): This pin provides the regulated output voltage. The output voltage is set using external resistors connected between the output, adjustment, and ground.
3. Adjustment (Adj): This pin is used to adjust the output voltage. By connecting a resistor divider between the output and ground, with the adjustment pin tied to the midpoint, the output voltage can be set precisely.
The LM317T-DG is commonly used in power supply applications where a stable and adjustable voltage is required.
