LM337T Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM337T is 40V, but it's recommended to keep it below 35V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, and keep the input and output capacitors close to the regulator. Also, use a low-ESR capacitor for the output capacitor.
  • The LM337T can regulate properly with a minimum load current of 3.5mA, but it's recommended to have a minimum load current of 10mA for optimal performance.
  • The LM337T is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures.
  • Use a TVS (Transient Voltage Suppressor) diode or a zener diode in parallel with the input capacitor to protect the LM337T from input voltage transients.
