LM2903DT Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM2903DT is 26V, but it's recommended to keep it below 24V for stable operation.
  • To ensure a stable 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 within the recommended range.
  • The LM2903DT is rated for operation up to 125°C, but its performance may degrade at high temperatures. Be sure to check the datasheet for thermal derating information and consider using a heat sink if necessary.
  • Use a TVS (transient voltage suppressor) diode or a voltage clamp circuit to protect the LM2903DT from input voltage transients. This will help prevent damage from voltage spikes or surges.
  • The LM2903DT is not a low-dropout regulator (LDO). It has a dropout voltage of around 2V, so it's not suitable for low-dropout applications. Consider using a dedicated LDO regulator instead.
