Instructions for Use:

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the specified range of 4.5V to 36V.
   • Avoid connecting voltages outside this range to prevent damage to the device.

2. Output Voltage (V_OUT):

   • The DDA002C provides a regulated output voltage of 5.0V.
   • Verify that the connected load can operate within this voltage range.

3. Output Current (I_OUT):

   • The maximum continuous output current is 2.0A, with a peak of 2.5A.
   • Ensure the load does not exceed these limits to avoid overheating or damage.

4. Quiescent Current (I_Q):

   • The device consumes a small amount of current (1.0 to 2.0mA) even when no load is present.
   • This should be considered in low-power applications.

5. Dropout Voltage (V_DO):

   • The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation.
   • For optimal performance, ensure the input voltage is at least 0.5V higher than the output voltage.

6. Line Regulation:

   • The output voltage remains stable despite variations in the input voltage.
   • The typical line regulation is 0.1%, with a maximum of 0.2%.

7. Load Regulation:

   • The output voltage remains stable despite changes in the load current.
   • The typical load regulation is 0.1%, with a maximum of 0.2%.

8. Ripple Rejection:

   • The device effectively reduces input ripple, with a typical rejection of 70dB and a maximum of 80dB.

9. Thermal Shutdown (T_SD):

   • The device will shut down if the temperature exceeds 160°C to prevent damage.
   • Ensure proper heat dissipation, especially under high load conditions.

10. Operating Temperature (T_OP):

    • The device can operate in ambient temperatures ranging from -40°C to 125°C.
    • Ensure the operating environment does not exceed these limits.

Additional Notes:

• Always use appropriate decoupling capacitors on both the input and output sides to improve stability and reduce noise.
• For high current applications, consider using a heatsink to manage thermal dissipation.
• Refer to the datasheet for detailed application circuits and additional technical information.
