LM2937IMPX-3.3/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation.

  • The device is rated for operation up to 125°C, but the output voltage may decrease at high temperatures. Ensure proper thermal design and heat sinking to maintain reliability.

  • Use a 10uF or larger output capacitor with a low ESR (Equivalent Series Resistance) to ensure stability and accuracy. Also, ensure the input capacitor is properly sized and placed close to the device.

  • A minimum of 1uF input capacitance is recommended, but 4.7uF or larger is recommended for optimal performance.

  • Yes, the device is suitable for battery-powered devices. However, ensure the input voltage is within the recommended range, and consider using a low-dropout regulator (LDO) for better efficiency.
