LM2903N Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2903N is 40V, but it's recommended to keep it below 35V for reliable operation.
  • The LM2903N 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 with an ESR of 5 ohms or less, and keep the input capacitance to a minimum (less than 1uF).
  • No, the LM2903N is a linear regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-power applications.
  • The minimum input voltage required for the LM2903N to regulate properly is 2.5V above the output voltage (e.g., 7.5V for a 5V output).
