LM4140BCMX-2.5/NOPB Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for voltage reference layouts, such as keeping the input and output traces short and separate, and using a solid ground plane to reduce noise.
  • To ensure stability, make sure to follow the recommended capacitor values and placement, and avoid using capacitors with high ESR. Also, keep the input and output impedance low, and use a buffer capacitor at the output if necessary.
  • The LM4140 has an operating temperature range of -40°C to 125°C, but it's recommended to derate the output voltage and current at higher temperatures to ensure reliability.
  • No, the LM4140 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, but it doesn't have the current capability or regulation features of a voltage regulator.
  • The output impedance of the LM4140 can be calculated using the equation Zout = (ΔVout / ΔIout) || Rload, where ΔVout is the change in output voltage, ΔIout is the change in output current, and Rload is the load resistance.
