LM2940CSX-9.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation.
  • Use a 10uF capacitor on the input and a 22uF capacitor on the output, and ensure the input voltage is at least 2V higher than the output voltage.
  • The minimum input voltage is 11V, but it's recommended to keep it above 12V for reliable operation.
  • The LM2940CSX-9.0/NOPB is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management.
  • Use a TVS diode or a transient voltage suppressor on the input to protect against voltage spikes and transients.
