LM2940CT-12/NOPB datasheet by Texas Instruments

LM2940CT-12/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2940CT-12/NOPB can handle?
  The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  Make sure to use the recommended output capacitor (10uF or larger) and input capacitor (1uF or larger) to ensure stability and regulation.
• Can I use the LM2940CT-12/NOPB in a high-temperature environment?
  The LM2940CT-12/NOPB is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management.
• How much current can the LM2940CT-12/NOPB supply?
  The LM2940CT-12/NOPB can supply up to 1A of output current, but it's recommended to keep it below 500mA for reliable operation.
• What is the dropout voltage of the LM2940CT-12/NOPB?
  The dropout voltage is typically around 1.5V, which means the input voltage should be at least 1.5V higher than the output voltage for proper regulation.
