Pinout
1. Input (Vin): Connects to the higher voltage input source.
2. Output (Vout): Provides the regulated 2.5V output.
3. Ground (GND): Common ground connection.
4. Adjust (ADJ): Adjust pin for setting output voltage (not present in fixed-output versions like the -2.5).
5. Shutdown (SHDN): Used to enable or disable the output voltage (active low).
Note that specific pin functions might slightly differ based on the package type or specific application configuration, so it's always recommended to consult the official datasheet for detailed pin configuration and usage.
