LM2940IMPX-10/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2940 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 value (10uF) and keep the input voltage within the recommended range. Also, ensure the device is properly decoupled from the input and output lines.
  • The minimum input voltage required for the LM2940 to operate is 7V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2940 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 LM2940 from input voltage surges or spikes, use a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input to limit the voltage to within the recommended range.
