Instructions for Use

1. Input Connection:

   • Connect the input voltage (VIN) to the input pin of the W6810IRG. Ensure the input voltage is within the specified range (2.7V to 5.5V).

2. Output Connection:

   • Connect the output pin (VOUT) to the load or circuit that requires a regulated 3.3V supply. The maximum continuous output current is 1.5A, with a typical output of 1A.

3. Ground Connection:

   • Ensure a common ground connection between the input and output circuits to maintain proper operation.

4. Capacitors:

   • Place a 10μF electrolytic capacitor close to the input pin to filter out noise and stabilize the input voltage.
   • Place a 10μF electrolytic capacitor close to the output pin to filter out any ripple and ensure stable output voltage.

5. Thermal Management:

   • The W6810IRG has a typical junction-to-ambient thermal resistance of 35°C/W. For high current applications, consider using a heatsink to dissipate heat effectively and prevent overheating.

6. Operating Temperature:

   • The device can operate over a wide temperature range from -40°C to 125°C. Ensure the ambient temperature does not exceed these limits to avoid damage.

7. Storage Temperature:

   • Store the device in a temperature range of -65°C to 150°C to prevent degradation.

8. Efficiency:

   • The typical efficiency of the W6810IRG is 90% at a 1A output current. Monitor the power dissipation to ensure it remains within safe limits.

9. Dropout Voltage:

   • The dropout voltage is typically 300mV at full load (1A). Ensure the input voltage is at least 300mV higher than the output voltage to maintain regulation.

10. Quiescent Current:

    • The quiescent current is typically 50μA and can go up to 100μA. This is the current consumed by the regulator when there is no load on the output.

By following these instructions, you can ensure reliable and efficient operation of the W6810IRG low-dropout linear regulator.
