Instructions for Using CQ1265RT

1. Power Supply Connection:

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

2. Ground Connection:

   • Connect the GND pin to the system ground.

3. Output Configuration:

   • Connect the load to the VOUT pin.
   • Ensure the output current does not exceed the maximum rating (100mA).

4. Capacitor Requirements:

   • Place a 1μF ceramic capacitor between VIN and GND as close to the device as possible.
   • Place a 10μF electrolytic capacitor between VOUT and GND to stabilize the output.

5. Thermal Management:

   • Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
   • Monitor the thermal shutdown temperature (160°C) to avoid damage.

6. Operating Conditions:

   • Operate the device within the specified temperature range (-40°C to 85°C).
   • Avoid exceeding the dropout voltage (0.3V) to maintain stable operation.

7. Efficiency Considerations:

   • The efficiency can vary from 80% to 95% depending on the load and input voltage.
   • Optimize the design for the best efficiency by selecting appropriate components and layout.

8. Regulation:

   • The load regulation is typically 0.5%, and the line regulation is 0.3%.
   • These parameters ensure stable output under varying load and input conditions.

9. Storage:

   • Store the device in a dry, cool environment to prevent damage.
   • Follow the storage temperature guidelines to ensure long-term reliability.

10. Handling:

    • Handle the device with care to avoid mechanical damage.
    • Use proper ESD protection when handling to prevent electrostatic discharge damage.
