Pinout

The LM317LZG is a voltage regulator with three pins. Its main function is to provide an adjustable output voltage ranging from 1.25V to 37V. The three pins are:
1. Input (Vin): This pin is connected to the unregulated input voltage which must be higher than the desired output voltage by at least 3V.

2. Output (Vout): This pin provides the regulated output voltage, which is adjusted based on the resistor network connected between the output and adjustment pins.

3. Adjustment (Adj): This pin is used to set the output voltage. By connecting a resistor between the output and adjustment pins and another resistor between the adjustment pin and ground, the output voltage can be adjusted based on the ratio of these resistors.
The LM317LZG is commonly used in applications requiring a stable and adjustable power supply. It features internal current limiting, thermal shutdown, and safe area compensation to ensure reliable operation.
