Instructions:

  1. Power Supply Connection:

    • Connect the input voltage (V_IN) to the input pin.
    • Ensure the input voltage is within the specified range (4.5V to 28V).

  2. Output Configuration:

    • The output voltage (V_OUT) is fixed at 3.3V.
    • Connect the output pin to your load.

  3. Grounding:

    • Connect the ground (GND) pin to the common ground of your circuit.

  4. Thermal Management:

    • Ensure proper heat dissipation, especially when operating at high output currents.
    • Use a heatsink if necessary to keep the junction temperature below 160°C.

  5. Capacitors:

    • Place a 10μF tantalum capacitor or a 10μF ceramic capacitor between the input and ground pins close to the device.
    • Place a 10μF tantalum capacitor or a 10μF ceramic capacitor between the output and ground pins close to the device.

  6. Load Regulation:

    • The load regulation is typically 1%, meaning the output voltage will change by 1% for variations in load current.

  7. Line Regulation:

    • The line regulation is typically 1%, meaning the output voltage will change by 1% for variations in input voltage.

  8. Thermal Shutdown:

    • The device will shut down if the junction temperature exceeds 160°C to prevent damage.

  9. Operating and Storage Temperature:

    • Ensure the device operates within the temperature range of -40°C to 125°C.
    • Store the device within the temperature range of -65°C to 150°C.

  10. Handling Precautions:

    • Handle the device with care to avoid static damage.
    • Follow proper soldering techniques to ensure reliable connections.
