LM337LZ/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM337LZ is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure a stable output voltage, make sure to use a minimum of 10uF capacitor at the output and a 0.1uF capacitor at the input, and keep the input voltage at least 2V higher than the output voltage.
  • Yes, the LM337LZ can be used as a variable voltage regulator by using a potentiometer to adjust the output voltage. However, the output voltage range is limited to 1.2V to 37V.
  • The LM337LZ can supply up to 1.5A of output current, but it's recommended to keep the output current below 1A for reliable operation.
  • The dropout voltage of the LM337LZ is typically around 2V, which means the input voltage should be at least 2V higher than the output voltage for proper regulation.
