LM340T-12/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 35V, but it's recommended to keep it below 25V for reliable operation.
  • The LM340T-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 to prevent overheating.
  • Use a high-quality input capacitor (e.g., 10uF) and a low-ESR output capacitor (e.g., 10uF) to minimize ripple and noise. Also, ensure the input voltage is well-regulated and within the recommended range.
  • The minimum input voltage is 14.5V, but it's recommended to keep it above 15.5V for reliable operation and to ensure the output voltage is within regulation.
  • No, the LM340T-12/NOPB is a linear voltage regulator and not suitable for switching power supply applications. It's designed for low-dropout, low-noise, and high-reliability applications.
