LM323K Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM323K is 42V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) should be between 0.5Ω and 10Ω.
  • The maximum current that the LM323K can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • To protect the LM323K from overheating, ensure good thermal conductivity between the device and the PCB, and consider adding a heat sink if the device will be operating at high temperatures or high currents.
  • The LM323K is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure good thermal design and consider derating the device for high-temperature operation.
