LM2937ES-3.3/NOPB datasheet by Texas Instruments

LM2937ES-3.3/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM2937ES-3.3/NOPB?
  The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation.
• Can I use the LM2937ES-3.3/NOPB in a high-temperature environment?
  The LM2937ES-3.3/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.
• How do I ensure the output voltage is stable and accurate?
  Use a 10uF or larger output capacitor with a low ESR (Equivalent Series Resistance) to ensure stability and accuracy. Also, ensure the input voltage is well-regulated and filtered.
• Can I use the LM2937ES-3.3/NOPB in a battery-powered device?
  Yes, the LM2937ES-3.3/NOPB is suitable for battery-powered devices. However, consider the quiescent current (IQ) and shutdown current to minimize battery drain when the device is in sleep mode.
• What is the minimum input voltage required for the LM2937ES-3.3/NOPB to function properly?
  The minimum input voltage is 5.5V, but it's recommended to keep it above 6V for reliable operation.
