LM337KCSE3 Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V for reliable operation.
  • Make sure to use a minimum of 10uF capacitor on the output and a minimum of 0.1uF capacitor on the input to ensure stability and regulation.
  • The maximum current that the LM337KCSE3 can supply is 1.5A, but it's recommended to keep it below 1A for reliable operation.
  • The output voltage can be adjusted by using a resistor divider network between the output and the adjust pin. The formula to calculate the output voltage is Vout = 1.25V * (1 + R1/R2).
  • The thermal shutdown temperature of the LM337KCSE3 is 150°C. The device will shut down when the junction temperature exceeds this value.
