LM2903D Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2903D is 26V, but it's recommended to keep it below 20V for reliable operation.

  • To ensure stability, a minimum output capacitance of 10uF is recommended, and the ESR (Equivalent Series Resistance) of the capacitor should be less than 5 ohms.

  • The maximum current that the LM2903D can supply is 1A, but it's recommended to keep it below 0.8A for reliable operation and to prevent overheating.

  • To protect the LM2903D from overheating, ensure good thermal conductivity between the device and the PCB, and consider adding a heat sink if the device will be operating at high temperatures or high currents.

  • The LM2903D is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure good thermal design and consider derating the device for high-temperature operation.
