Instructions for BD7682FJ-LBE2

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply ensuring it is within the range of 4.5V to 18V.
   • Ensure proper bypass capacitors are placed close to the input and output pins to maintain stability.

2. Output Voltage Setting:

   • Use external resistors to set the desired output voltage (VOUT). Refer to the datasheet for the resistor values required for your specific output voltage.

3. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.
   • The device features thermal shutdown protection but should not be relied upon as a primary cooling method.

4. Layout Guidelines:

   • Keep the layout compact to minimize noise and improve transient response.
   • Place the input and output capacitors as close as possible to the respective pins.

5. Operating Temperature Range:

   • Ensure that the operating temperature stays within -40°C to +85°C for reliable operation.

6. Enable Pin:

   • The enable pin can be used to control the on/off state of the regulator. Pull this pin high to enable the regulator and low to disable it.

7. Protection Features:

   • The device includes overcurrent protection, short-circuit protection, and thermal shutdown to protect against various fault conditions.
