LM337D2TR4G Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • Use a 10uF or larger output capacitor to ensure stability and accuracy. Also, make sure the input capacitor is at least 1uF.
  • The minimum input voltage is 3V, but it's recommended to keep it above 4.5V for reliable operation.
  • The LM337D2TR4G is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management.
  • Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect against voltage transients.
