LM2903NG Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2903NG is 40V, but it's recommended to keep it below 35V for reliable operation.
  • The LM2903NG 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. Also, avoid using long input wires and keep the input and output pins as close as possible.
  • No, the LM2903NG is a linear voltage regulator and is not suitable for use in switching regulator applications. It's designed for low-dropout, low-noise, and high-PSRR applications.
  • The minimum input voltage required for the LM2903NG to regulate the output voltage is typically 2.5V above the output voltage. For example, for a 5V output, the minimum input voltage would be 7.5V.
