Instructions for Use

  1. Power Supply Connection:

    • Connect the input voltage (VIN) to the power supply within the specified range (4.5V to 5.5V).
    • Ensure the power supply is stable and capable of providing the required current.
  2. Output Connection:

    • Connect the output (VOUT) to the load requiring 3.3V.
    • The maximum continuous output current is 1.2A, with a peak of 1.5A.
  3. Ground Connection:

    • Ensure a common ground connection between the input, output, and load to maintain proper operation.
  4. Thermal Management:

    • The device has a typical junction-to-ambient thermal resistance of 50°C/W. Use appropriate heatsinking if operating at high temperatures or under high load conditions.
    • Ensure the operating temperature does not exceed 85°C.
  5. Load Regulation:

    • The load regulation is typically 0.5% to 1.0%, meaning the output voltage will vary slightly with changes in load current.
  6. Line Regulation:

    • The line regulation is typically 0.2% to 0.5%, indicating that the output voltage will remain relatively stable even with variations in input voltage.
  7. Ripple Rejection:

    • The device provides 60dB to 70dB of ripple rejection, effectively filtering out input voltage noise.
  8. Storage:

    • Store the device in a dry environment within the storage temperature range (-65°C to 150°C).
  9. Handling:

    • Handle the device with care to avoid mechanical damage or static discharge, which can affect performance.
  10. Testing:

    • Before integrating the device into a larger system, test it under various load and input conditions to ensure it meets the required specifications.
