LM2940T-5.0 Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2940T-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 ceramic capacitor between the ADJ pin and GND, and a 2.2μF capacitor between the OUTPUT pin and GND. Also, make sure the input voltage is within the recommended range.

  • The minimum input voltage required for the LM2940T-5.0 to function is 7.5V, but it's recommended to keep it above 8V for reliable operation.

  • The LM2940T-5.0 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.

  • To protect the LM2940T-5.0 from input voltage transients, use a TVS diode or a transient voltage suppressor between the input pin and GND. This will help absorb voltage spikes and ensure the regulator operates within its specified range.
