Instructions for Use:

1. Supply Voltage:

   • Ensure the supply voltage (VCC) is within the range of 4.5V to 5.5V to avoid damage or improper operation.

2. Output Current:

   • The BD680G can provide a continuous output current of up to 1.2A with a peak current of up to 2.5A. Ensure that the load does not exceed these limits to prevent overheating and potential failure.

3. Quiescent Current:

   • The quiescent current (IQ) is the current consumed by the regulator when there is no load. It typically ranges from 10mA to 30mA at 5V supply.

4. Dropout Voltage:

   • The dropout voltage (VD) is the minimum difference between the input and output voltages required for the regulator to maintain regulation. It is typically between 0.5V and 1.5V at an output current of 1A.

5. Thermal Shutdown:

   • The regulator includes thermal protection that activates at temperatures between 150掳C and 170掳C to prevent damage from excessive heat. Ensure adequate heat dissipation to keep the temperature within safe operating limits.

6. Operating Temperature:

   • The BD680G is designed to operate within a temperature range of -40掳C to 85掳C. Avoid operating the device outside this range to ensure reliable performance.

7. Storage Temperature:

   • When storing the BD680G, keep it within a temperature range of -65掳C to 150掳C to prevent damage.

8. Mounting and Layout:

   • Use a proper heat sink if the regulator will be subjected to high current or high ambient temperatures. Ensure good thermal conductivity between the regulator and the heat sink.
   • Keep the input and output capacitors close to the regulator to minimize noise and improve stability.

9. Capacitors:

   • Use a 10渭F tantalum or ceramic capacitor on the input side and a 10渭F tantalum or ceramic capacitor on the output side to ensure stable operation and reduce ripple.

10. Polarity:

    • Ensure correct polarity when connecting the BD680G to the power supply and load. Reversing the polarity can cause damage to the regulator.
