LM2903DR Frequently Asked Questions (FAQs)

  • The maximum input voltage for the LM2903DR is 30V, but it's recommended to keep it below 25V 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 LM2903DR 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 if you expect high temperatures.
  • The LM2903DR can deliver up to 1A of output current, but it's recommended to keep the output current below 500mA for stable operation.
  • While the LM2903DR is a general-purpose voltage regulator, it's not specifically designed for automotive applications. For automotive use, consider using a regulator with specific automotive-grade qualifications, such as AEC-Q100.
