Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage (V_IN) to the power supply.
   • Ensure the input voltage is within the specified range (8V to 40V).

2. Output Connection:

   • Connect the output voltage (V_OUT) to the load.
   • The output voltage is fixed at 5V.

3. Ground Connection:

   • Connect the ground (GND) to both the power supply and the load.

4. Heat Dissipation:

   • If operating at high output currents, ensure proper heat dissipation to maintain the junction temperature within safe limits.
   • Consider using a heatsink if the thermal resistance (θJA) is a concern.

5. Capacitors:

   • For stable operation, use a 10μF electrolytic capacitor on the input side and a 10μF ceramic capacitor on the output side.
   • Place these capacitors as close as possible to the device.

6. Operating Environment:

   • Operate the device within the specified temperature ranges to avoid damage or performance degradation.
   • The operating temperature range is -40°C to 125°C, and the storage temperature range is -65°C to 150°C.

7. Ripple Rejection:

   • The device provides good ripple rejection, but for optimal performance, ensure that the input voltage is clean and stable.

8. Load Regulation:

   • The load regulation is specified to be within 0.5% to 1% over the full load range (0 to 3A).

9. Line Regulation:

   • The line regulation is specified to be within 0.1% to 0.5% over the input voltage range (8V to 40V).

10. Storage and Handling:

    • Store the device in a dry, cool place.
    • Handle with care to avoid mechanical stress or damage.

By following these instructions, you can ensure reliable and efficient operation of the DTA143ZKA.
