Pinout
1. Input (Pin 3): This pin is where the unregulated input voltage is applied.
2. Output (Pin 4): This pin provides the regulated output voltage.
3. Adjust (Pin 2): This pin is used to set the output voltage by connecting it to a resistor divider network.
The remaining pins in the package are typically not connected to functional circuits within the device or are used for additional stability and heat dissipation purposes. The TL317 is similar in function to the LM317 but may come in different package and performance specifications. It is capable of driving a wide range of output currents and can adjust the output voltage over a wide range by changing the resistors connected to the adjust pin.
