LM399AH#PBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LM399AH involves keeping the input and output traces short and separate, using a solid ground plane, and placing the device close to the power supply bypass capacitors. A 4-layer PCB with a dedicated ground plane is recommended.
  • To ensure stability, make sure to follow the recommended PCB layout, use a minimum of 10uF capacitance on the output, and keep the input and output impedance low. Also, avoid using long input traces and keep the device away from noise sources.
  • The maximum power dissipation of the LM399AH is 1.4W. However, it's recommended to derate the power dissipation based on the ambient temperature and the thermal resistance of the package.
  • Yes, the LM399AH is rated for operation up to 125°C. However, the voltage reference accuracy and stability may degrade at high temperatures. It's recommended to consult the datasheet and application notes for more information on high-temperature operation.
  • To protect the LM399AH from EOS, use a voltage limiter or a transient voltage suppressor (TVS) on the input, and ensure that the input voltage does not exceed the maximum rating. Also, use a fuse or a current limiter to prevent excessive current.
