LM4050CEM3-2.5/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-grounded layout with the voltage reference at the center, and keeping the input and output traces as short as possible to minimize noise and parasitic inductance.
  • The LM4050CEM3-2.5/NOPB has a thermal shutdown feature that activates at 150°C. Ensure good thermal conduction by using a thermal pad or heat sink, and keep the device away from heat sources. Also, consider the thermal resistance of the PCB and surrounding components.
  • Texas Instruments recommends a 10uF to 22uF ceramic capacitor with a voltage rating of at least 6.3V, placed as close as possible to the VIN pin to filter out noise and ensure stable operation.
  • No, the LM4050CEM3-2.5/NOPB is a voltage reference, not a voltage regulator. It is designed to provide a stable voltage reference, but it does not have the capability to regulate voltage or provide a high current output.
  • The LM4050CEM3-2.5/NOPB has a specified temperature coefficient of 10ppm/°C. To ensure accuracy, use a high-precision resistor network, and consider using a temperature compensation circuit or a thermistor to compensate for temperature variations.
