LM2940CS-5.0/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2940CS-5.0/NOPB is 26V, but it's recommended to keep it below 20V for reliable operation.

  • To ensure a stable and regulated output voltage, make sure to use the recommended output capacitor (10uF) and input capacitor (10uF) values, and keep the input voltage within the recommended range.

  • The minimum input voltage required for the LM2940CS-5.0/NOPB to operate is 7V, but it's recommended to keep it above 8V for reliable operation.

  • The LM2940CS-5.0/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation.

  • To protect the LM2940CS-5.0/NOPB from input voltage transients, use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to clamp the input voltage.
