Instructions for Use:

  1. Input Connection:

    • Connect the input voltage to the "Input" pin (Pin 1). Ensure the input voltage is within the specified range (14.5V to 35V).
  2. Output Connection:

    • Connect the load to the "Output" pin (Pin 2). The output voltage will be regulated to 12V.
  3. Ground Connection:

    • Connect the ground to the "Common" pin (Pin 3).
  4. Capacitors:

    • For stable operation, it is recommended to place a 0.33μF capacitor between the input pin and ground, and a 0.1μF capacitor between the output pin and ground.
  5. Thermal Considerations:

    • The L7812 has thermal shutdown protection, but it is advisable to use a heatsink if the device is expected to dissipate significant power (e.g., when the input voltage is high or the output current is close to the maximum).
  6. Short-Circuit Protection:

    • The L7812 includes internal short-circuit protection, which will limit the output current to prevent damage in case of a short circuit.
  7. Mounting:

    • Ensure proper mounting to a PCB or heatsink to maintain good thermal performance.
  8. Storage:

    • Store the L7812 in a dry, cool place to avoid damage from moisture or extreme temperatures.
