Instructions for Use

1. Supply Voltage (Vcc):

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

2. Output Current (Iout):

   • The continuous output current should not exceed 300mA. For peak currents, up to 600mA can be handled in short pulses.

3. Quiescent Current (Iq):

   • The quiescent current is very low, typically around 5μA, making the LB1979 suitable for low-power applications.

4. Dropout Voltage (Vdo):

   • The dropout voltage is the difference between the input and output voltages at which the regulator can no longer maintain regulation. It is typically 0.5V at 100mA.

5. Thermal Shutdown (Tshut):

   • The device will automatically shut down if the temperature exceeds 150°C to prevent damage. Allow the device to cool before resuming operation.

6. Operating Temperature (Topr):

   • The operating temperature range is from -40°C to 85°C. Ensure that the device is used within this range to maintain reliability and performance.

Additional Notes

• Capacitors:
  • Use appropriate input and output capacitors to stabilize the supply and ensure proper regulation.
• PCB Layout:
  • Ensure good thermal management by providing adequate copper area for heat dissipation.
• Polarity:
  • Observe correct polarity when connecting the device to avoid damage.
