LM2937ET-12/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation.

  • The LM2937ET-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 10uF or larger output capacitor with a low ESR (Equivalent Series Resistance) to ensure stability and accuracy. Also, ensure the input voltage is well-regulated and filtered.

  • The minimum input voltage is 7.5V, but it's recommended to keep it above 8.5V for reliable operation.

  • No, the LM2937ET-12/NOPB is a linear voltage regulator and not suitable for switching power supply applications. It's designed for low-dropout, low-power applications.
