The maximum input voltage is 26V, but it's recommended to keep it below 20V for reliable operation.
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.
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.
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.
The minimum input voltage is 5.5V, but it's recommended to keep it above 6V for reliable operation.
