LM7809CT Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM7809CT is 35V, but it's recommended to keep it below 25V for reliable operation.
  • The LM7809CT 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 input voltage at high temperatures.
  • To ensure stability, use a minimum output capacitance of 10uF and an input capacitance of 0.33uF to 1uF. Also, keep the input voltage at least 2V higher than the output voltage.
  • No, the LM7809CT is a linear regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-noise, and high-reliability applications.
  • The minimum input voltage required for the LM7809CT to regulate properly is 11V, but it's recommended to keep it above 12V for reliable operation.
