LM2941LD Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2941LD is 26V, but it's recommended to keep it below 20V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 22uF with an ESR of 0.05 ohms or less, and keep the input capacitance as close to the regulator as possible.
  • The minimum input voltage required for the LM2941LD to regulate properly is 7.5V for the 5V version and 9.5V for the 12V version.
  • The LM2941LD is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Derate the output current accordingly for high-temperature operation.
  • Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the LM2941LD from input voltage transients.
