Instructions for FR4105

1. Power Supply Connection:

   • Connect the input voltage within the specified range (4.5V to 55V) to the VIN pin.
   • Ensure a stable power supply to avoid fluctuations that could affect performance.

2. Output Configuration:

   • The device can provide up to 1.5A continuous output current. Ensure your load does not exceed this limit.
   • Use appropriate external components like inductors and capacitors as recommended in the datasheet for optimal performance.

3. Thermal Considerations:

   • Operate within the ambient temperature range of -40°C to +85°C.
   • For extended periods of high current operation, ensure adequate heat dissipation.

4. Protection Features:

   • The FR4105 includes overcurrent and thermal shutdown protections. These features will activate if the device detects abnormal conditions to prevent damage.

5. Mounting and Handling:

   • Mount the device using standard techniques for the TO-220 package.
   • Handle with care to avoid damage to pins or the body of the component.

6. Storage:

   • Store the device in a dry place within the temperature range of -55°C to +125°C when not in use.

For detailed specifications and more complex applications, refer to the full datasheet provided by the manufacturer.
