LM2940CT-12 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2940CT-12 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 above the dropout voltage (around 1.5V).
  • The minimum input voltage required for the LM2940CT-12 to operate is around 7.5V, but it's recommended to keep it above 8V for reliable operation.
  • The LM2940CT-12 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 LM2940CT-12 from input voltage transients, use a TVS diode or a transient voltage suppressor at the input, and consider adding a fuse or a PTC resettable fuse for overcurrent protection.
