LM2940CT-5.0 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2940CT-5.0 is 26V, but it's recommended to keep it below 20V for reliable operation.

  • To ensure the output voltage is exactly 5.0V, use a 10nF capacitor on the output pin and a 10uF capacitor on the input pin. Also, make sure the input voltage is within the recommended range.

  • The minimum input voltage required for the LM2940CT-5.0 to function is 7.5V, but it's recommended to keep it above 8V for reliable operation.

  • The LM2940CT-5.0 is rated for operation up to 125°C, but it's recommended to keep the junction temperature below 115°C for reliable operation. Use a heat sink if necessary.

  • Use a TVS diode or a transient voltage suppressor on the input pin to protect the LM2940CT-5.0 from input voltage transients.
