LM2903DRG3 Frequently Asked Questions (FAQ)

  • The maximum input voltage for the LM2903DRG3 is 40V, but it's recommended to keep it below 35V for reliable operation.

  • The LM2903DRG3 is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper heat sinking and thermal management to prevent overheating.

  • Use a high-quality output capacitor with a minimum value of 10uF, and ensure the input capacitor is at least 1uF. Also, keep the output voltage sensing pin (Vout) close to the output capacitor to minimize noise and ensure accurate regulation.

  • The minimum input voltage required for proper regulation is 7.5V, but it's recommended to keep it above 8.5V for optimal performance.

  • While the LM2903DRG3 can be used in switching power supplies, it's not the most suitable choice due to its relatively low switching frequency (100 kHz). Consider using a dedicated switching regulator IC for high-frequency switching applications.
