Pinout
1. Vin (Input): This pin receives the unregulated input voltage that you wish to regulate.
2. Vout (Output): This pin outputs the regulated voltage. The output voltage can be adjusted using an external resistor network.
3. ADJ (Adjust): This pin is used to adjust the output voltage. By connecting a voltage divider between the output and ground, with this pin tapping into the divider, you can set the desired output voltage.
The LM317 can supply an output voltage ranging from 1.25V to 37V and deliver a current of up to 100 mA in the surface-mount version. It is widely used for its simplicity, reliability, and flexibility in various applications where adjustable output is required.
