LM2940T-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.
  • The LM2940T-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 10uF or larger output capacitor with an ESR of 0.5 ohms or less to ensure stability and accuracy. Also, ensure the input voltage is well-regulated and filtered.
  • The minimum input voltage is 11V, but it's recommended to keep it above 12V for reliable operation.
  • No, the LM2940T-9.0/NOPB is a linear voltage regulator and not suitable for switching power supply applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
