LM2940S-12/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 layout is designed to minimize noise and electromagnetic interference (EMI).
  • The minimum input voltage is 14.5V, but it's recommended to keep it above 15V for reliable operation.
  • The LM2940S-12/NOPB is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.
  • Use a transient voltage suppressor (TVS) diode or a voltage clamp on the input to protect against voltage surges and spikes.
