Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply within the specified range of 4.5V to 16V.
   • Ensure proper bypass capacitors are placed close to the input and output pins.

2. Output Configuration:

   • The EN5311QI provides a fixed output voltage of 3.3V. No external components are required for voltage setting.

3. Thermal Considerations:

   • Place the device in an area with adequate airflow or cooling to prevent overheating, especially when operating near the maximum output current.

4. Protection Features:

   • The device includes over-current and over-temperature protection. In case of fault conditions, the device will automatically shut down to protect itself.

5. Layout Recommendations:

   • Keep the layout compact to minimize noise and parasitic effects. Use wide traces for power paths to reduce resistance and potential heating.

6. Handling Precautions:

   • Handle the component with care to avoid damage from electrostatic discharge (ESD). Follow standard ESD handling procedures.

7. Storage:

   • Store in a dry, cool place away from direct sunlight and moisture to ensure long-term reliability.
