Instructions for Use:

1. Input Connection: Connect the input voltage to the VIN pin and ensure it is within the specified range.
2. Output Configuration:
   • For adjustable output, connect a resistor divider between VOUT, FB, and GND.
   • Set the desired output voltage using the formula ( V_ = 1.23 times (1 + frac) ).
3. Output Capacitor: Place a capacitor at the output for stability and filtering; typically a 10渭F ceramic or electrolytic capacitor.
4. Inductor Selection: Choose an inductor based on the switching frequency and current requirements; typically 10渭H to 100渭H.
5. Layout Considerations: Ensure short, wide traces for power connections and place decoupling capacitors close to the IC.
6. Thermal Management: Provide adequate heat sinking if operating near maximum load conditions.

For detailed design considerations and specific applications, refer to the datasheet provided by the manufacturer.
