LM2903PWR Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM2903PWR 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 (e.g., 10uF) and a minimum load current of 5mA. Also, keep the input voltage ripple within 1V peak-to-peak.
  • The LM2903PWR is rated for operation up to 125°C, but its performance may degrade at high temperatures. Consider using a heat sink or a thermally-enhanced package (e.g., LM2903PWRG) for high-temperature applications.
  • Use a voltage clamp or a transient voltage suppressor (TVS) diode at the input to protect the LM2903PWR from voltage surges or spikes. You can also add a series resistor and a capacitor to filter out high-frequency noise.
  • No, the LM2903PWR is not designed as a low-dropout regulator. It requires a minimum input-to-output voltage differential of 2V to maintain regulation. For LDO applications, consider using a dedicated LDO regulator like the TLV703P.
