Instructions for NCP1081DER2G

1. Input Connection:

   • Connect the input voltage between the IN pin and GND. Ensure that the input voltage is within the specified operating range (2.5V to 40V).

2. Output Configuration:

   • The output voltage is fixed at 3.3V. No external components are required for setting the output voltage.

3. Capacitor Selection:

   • Use a ceramic capacitor of at least 1渭F on the input side (between IN and GND).
   • A 1渭F ceramic capacitor should also be placed on the output side (between OUT and GND) for stability.

4. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at higher temperatures or under high load conditions.
   • Place the device in areas with good airflow or use a heatsink if necessary.

5. Layout Recommendations:

   • Keep the input and output capacitors as close as possible to the respective pins.
   • Minimize trace lengths to reduce parasitic inductance and resistance.

6. Handling Precautions:

   • Handle the component carefully to avoid damage from electrostatic discharge (ESD).
   • Follow standard ESD protection guidelines during assembly and handling.
