Instructions for Use:

  1. Power Supply Connection:

    • Connect the input voltage (VIN) to the Vin pin.
    • Connect the output voltage (VOUT) to the Vout pin.
    • Ensure the ground (GND) is connected to the common ground of the system.
  2. Capacitors:

    • Place a 0.1μF ceramic capacitor close to the Vout pin to stabilize the output voltage.
    • Optionally, add a 10μF electrolytic capacitor between Vout and GND for better ripple rejection.
  3. Thermal Management:

    • The NJM79M12FA has a thermal shutdown feature to protect against overheating.
    • For high current applications, ensure adequate heat dissipation by using a heatsink or placing the device on a large copper area.
  4. Input Voltage Range:

    • The input voltage should be at least 1.5V higher than the output voltage to ensure proper operation.
    • The maximum input voltage is 24V.
  5. Output Current:

    • The maximum continuous output current is 150mA.
    • Ensure that the load does not exceed this limit to avoid overheating and potential damage.
  6. Operating Temperature:

    • The device is designed to operate within the temperature range of -40°C to 85°C.
    • Store the device in an environment with temperatures ranging from -65°C to 150°C.
  7. Handling Precautions:

    • Handle the device with care to avoid static damage.
    • Follow standard ESD (Electrostatic Discharge) precautions during handling and installation.
  8. Mounting:

    • Solder the device to the PCB using a temperature-controlled soldering iron.
    • Avoid excessive heat during soldering to prevent damage to the device.

By following these instructions, you can ensure reliable and efficient operation of the NJM79M12FA voltage regulator.
