Instructions for Use:

1. Mounting and Orientation:

   • Ensure the W117SIP-18 is correctly oriented on the PCB as per the datasheet diagram.
   • Securely mount the component ensuring proper heat dissipation if required.

2. Input Voltage Consideration:

   • The input voltage must be within the specified range of 3V to 30V.
   • Ensure that the input voltage exceeds the desired output voltage by at least the dropout voltage (1.7V).

3. Output Voltage Setting:

   • Adjust the external resistors connected to the ADJ pin to set the desired output voltage.
   • Follow the formula provided in the datasheet to calculate resistor values.

4. Capacitor Requirements:

   • Place a bypass capacitor (typically 0.33渭F) between the input and ground close to the device.
   • A capacitor (typically 1渭F) should be placed between the output and ground to ensure stability.

5. Thermal Considerations:

   • Monitor the junction temperature to avoid exceeding the maximum operating temperature of 125掳C.
   • Use a heatsink if necessary, especially under high load conditions.

6. Testing:

   • After assembly, test the circuit to confirm the output voltage and functionality.
   • Verify the ripple rejection and regulation parameters meet the design requirements.
