LM2903QD Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM2903QD is 26V, but it's recommended to keep it below 24V for reliable operation.
  • To ensure a stable and accurate output voltage, make sure to use a suitable output capacitor with a minimum value of 10uF, and a maximum ESR of 5 ohms. Also, keep the input voltage ripple below 1V.
  • The LM2903QD is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to derate the output current and input voltage according to the datasheet's thermal derating curves.
  • Use a TVS (Transient Voltage Suppressor) diode or a voltage clamp circuit at the input to protect the LM2903QD from voltage surges and spikes.
  • The LM2903QD is not a low-dropout regulator, and it requires a minimum input-to-output voltage differential of 2V. If you need a low-dropout regulator, consider using a different device, such as the TLV703 or TPS63051.
