Parameter Table

Instructions

1. Supply Voltage (V_cc):

   • Ensure the supply voltage is within the range of 2.7V to 44V.
   • Use appropriate input filtering capacitors to reduce noise and ripple.

2. Output Current (I_out):

   • The LM675T/NOPB can provide up to 5A of continuous output current.
   • For higher currents, ensure adequate heat sinking to manage power dissipation.

3. Quiescent Current (I_q):

   • The quiescent current is typically 10mA when there is no load.
   • This value may increase with higher output currents.

4. Thermal Shutdown (T_shut):

   • The device will shut down if the junction temperature exceeds 175°C.
   • Use a heatsink to keep the temperature within safe operating limits.

5. Operating Junction Temperature (T_jop):

   • The operating junction temperature range is from -40°C to 150°C.
   • Ensure the device is not operated outside this range to avoid damage.

6. Storage Temperature (T_stg):

   • The storage temperature range is from -65°C to 150°C.
   • Store the device in a dry environment to prevent moisture damage.

7. Power Dissipation (P_d):

   • The maximum power dissipation is 40W for the TO-220 package.
   • Use a heatsink to dissipate excess heat, especially at high output currents.

8. Input Voltage Range (V_in):

   • The input voltage should be within the range of 2.7V to 44V.
   • Ensure the input voltage is stable and within the specified range to avoid damage.

9. Output Voltage Range (V_out):

   • The output voltage can be set from 1.2V to 44V using external resistors.
   • Follow the datasheet for resistor values to achieve the desired output voltage.

10. Line Regulation:

    • The line regulation is typically 0.01% per volt.
    • This indicates the stability of the output voltage with respect to changes in the input voltage.

11. Load Regulation:

    • The load regulation is typically 0.01% per ampere.
    • This indicates the stability of the output voltage with respect to changes in the load current.

12. Rise and Fall Time:

    • The rise and fall times are typically 5μs.
    • These values can be affected by the output capacitance and load conditions.

Additional Notes:

• Always refer to the datasheet for detailed information and specific application notes.
• Proper PCB layout and component selection are crucial for optimal performance and reliability.
• Use appropriate decoupling capacitors near the input and output pins to improve stability and reduce noise.
