LM2940CT-15 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2940CT-15 is 26V, but it's recommended to keep it below 20V for reliable operation.
  • To ensure a stable output voltage, make sure to use a minimum of 10uF capacitor at the input and a minimum of 22uF capacitor at the output, and keep the input voltage at least 2V higher than the output voltage.
  • The LM2940CT-15 can supply up to 1A of output current, but it's recommended to keep it below 500mA for reliable operation and to prevent overheating.
  • To protect the LM2940CT-15 from overheating, make sure to provide adequate heat sinking, keep the device away from high-temperature environments, and avoid operating it at maximum current and voltage for extended periods.
  • The LM2940CT-15 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 and ensure good airflow to keep the device cool.
