LM2940S-5.0 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2940S-5.0 is 26V, but it's recommended to keep it below 20V for reliable operation.
  • The LM2940S-5.0 is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and input voltage at high temperatures.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the output capacitor close to the regulator. Also, ensure that the input capacitor is at least 10uF and is placed close to the input pin.
  • The LM2940S-5.0 is not a low-dropout regulator, and it requires a minimum input-to-output voltage differential of 2V for proper operation. If you need a low-dropout regulator, consider using a different part.
  • Use a transient voltage suppressor (TVS) diode or a zener diode in parallel with the input capacitor to protect the regulator from input voltage transients.
