Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the positive terminal and ground (GND) to the negative terminal.
   • Ensure the input voltage is within the specified range (4.5V to 16V).

2. Output Configuration:

   • Adjust the output voltage (VOUT) using the external resistor network if the module is not pre-set.
   • The output voltage can be set between 3.3V and 5V.

3. Load Connection:

   • Connect the load to the output terminals (VOUT and GND).
   • Ensure the load current does not exceed 250mA.

4. Thermal Management:

   • Ensure adequate heat dissipation, especially at higher input voltages and output currents.
   • Use a heatsink if necessary to keep the operating temperature within the specified range.

5. Testing:

   • Before connecting the load, test the output voltage with a multimeter to ensure it is within the desired range.
   • Monitor the temperature and efficiency during operation to ensure optimal performance.

6. Storage:

   • Store the module in a dry environment within the storage temperature range (-55掳C to 125掳C).

7. Safety:

   • Do not exceed the maximum ratings to avoid damage to the module.
   • Ensure proper grounding and isolation to prevent electrical hazards.
