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).
Output Configuration:
- The output voltage is fixed at 3.3V. No external components are required for setting the output voltage.
Capacitor Selection:
- Use a ceramic capacitor of at least 1μF on the input side (between IN and GND).
- A 1μF ceramic capacitor should also be placed on the output side (between OUT and GND) for stability.
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.
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.
Handling Precautions:
- Handle the component carefully to avoid damage from electrostatic discharge (ESD).
- Follow standard ESD protection guidelines during assembly and handling.
