The LM317S is a three-terminal adjustable voltage regulator. It is commonly used to provide a stable output voltage that can be adjusted from 1.25V to 37V with an output current of up to 1.5A. The pin count and functions are as follows:
1. Input (VIN): This is the input pin where the unregulated voltage is applied. It supplies the voltage to the internal circuitry and the load.
2. Output (VOUT): This pin supplies the regulated output voltage to the load. The voltage is adjusted by changing the resistance in the feedback network between the output and the adjustment pin.
3. Adjust (ADJ): This pin is used to adjust the output voltage. By connecting a resistor divider between the output and the adjust pin, the output voltage can be set to the desired level.
The LM317S requires external resistors to set the output voltage and is used with capacitors to improve the transient response and stability.
