LM2903DG Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2903DG is 26V, but it's recommended to keep it below 24V for reliable operation.

  • The LM2903DG 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 LM2903DG 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 LM2903DG to regulate properly is 7.2V for a 5V output, and 10.2V for a 9V output.
