Instructions for Use:

  1. Input Voltage:

    • Ensure the input voltage is within the specified range (13.5V to 22.0V). Exceeding this range can damage the regulator.
  2. Output Voltage:

    • The output voltage is fixed at 12V with a tolerance of ±5%.
  3. Output Current:

    • The maximum output current is 100mA. Do not exceed this limit to avoid overheating and potential damage.
  4. Thermal Considerations:

    • The device has thermal shutdown protection that activates at approximately 160°C. Ensure adequate heat dissipation, especially under high load conditions.
    • The operating junction temperature range is from -40°C to 125°C. Avoid operating the device outside this range to prevent reliability issues.
  5. Capacitors:

    • It is recommended to use a 0.1μF ceramic capacitor at the input and a 1μF tantalum or electrolytic capacitor at the output for stability and transient response.
  6. Mounting:

    • Mount the regulator on a PCB with good thermal conductivity to help dissipate heat. Use a heatsink if necessary, especially for continuous high-load applications.
  7. Storage:

    • Store the device in a dry environment within the storage temperature range of -65°C to 150°C to maintain its performance and reliability.
  8. Handling:

    • Handle the device with care to avoid mechanical stress and static electricity, which can damage the internal components.
  9. Testing:

    • Before finalizing the design, test the regulator under various operating conditions to ensure it meets the required specifications.
  10. Compliance:

    • Ensure that the application complies with relevant safety and regulatory standards, especially for products intended for consumer use.
