LM2903DR Frequently Asked Questions (FAQ)

  • The maximum input voltage for the LM2903DR is 26V, but it's recommended to keep it below 25V for reliable operation.

  • The LM2903DR 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 below 10uF.

  • No, the LM2903DR is a linear voltage regulator and not suitable for switching regulator applications. It's designed for low-dropout, low-power applications.

  • The minimum input voltage required for the LM2903DR to regulate the output voltage is typically 2.5V above the output voltage (e.g., 7.5V for a 5V output).
