Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V.
   • Use appropriate decoupling capacitors (typically 1μF ceramic) close to the VIN pin to stabilize the input.

2. Output Voltage (VOUT):

   • The FAN5056MV85 is pre-set to provide a fixed output voltage of 3.3V.
   • No external components are required to set the output voltage.

3. Output Current (IOUT):

   • The device can deliver up to 850mA of continuous output current.
   • Ensure proper heat dissipation if operating near the maximum current to avoid overheating.

4. Quiescent Current (IQ):

   • The quiescent current is typically 40μA, which is relatively low, making it suitable for battery-powered applications.

5. Shutdown Mode:

   • To put the device into shutdown mode, pull the SHDN pin low.
   • The shutdown current is typically 1μA, which helps to minimize power consumption when not in use.

6. Thermal Management:

   • The thermal resistance (θJA) is typically 50°C/W. Ensure adequate airflow or a heatsink if operating in high-temperature environments or at high output currents.

7. Operating and Storage Temperature:

   • The device operates over a temperature range of -40°C to 85°C.
   • Store the device between -65°C and 150°C.

8. Package:

   • The FAN5056MV85 comes in a SOT-23 package, which is small and easy to solder.

9. PCB Layout:

   • Place the input and output capacitors as close as possible to the respective pins to minimize parasitic inductance.
   • Ensure a good ground plane to help with heat dissipation and reduce noise.

10. Safety Considerations:

    • Do not exceed the maximum ratings specified in the datasheet.
    • Use appropriate fuses or current-limiting resistors to protect against short circuits.
