LM2937ET-5.0/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 26V, but it's recommended to keep it below 24V for reliable operation.

  • The LM2937ET-5.0/NOPB 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 low ESR (Equivalent Series Resistance) and ensure the input voltage is well-regulated. Also, follow the recommended PCB layout and decoupling capacitor placement guidelines.

  • The minimum input voltage is 7.2V, but it's recommended to keep it above 7.5V for reliable operation and to ensure the output voltage is within regulation.

  • Yes, the LM2937ET-5.0/NOPB is suitable for battery-powered devices. However, consider the quiescent current (IQ) and shutdown current (ISD) to minimize power consumption and extend battery life.
