REF1004I-1.2/2K5 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a star-grounded layout with the REF1004I-1.2/2K5 at the center, and using a solid ground plane to reduce noise. Additionally, keep the input and output traces separate and away from high-frequency signals.
  • To ensure stability and accuracy over temperature, use a low-ESR capacitor (e.g., 10uF) between the VOUT and GND pins, and a 1uF capacitor between the VIN and GND pins. Also, keep the device away from heat sources and ensure good airflow.
  • Although the datasheet specifies a maximum input voltage of 12V, it's recommended to limit the input voltage to 10V to ensure reliable operation and prevent damage to the device.
  • No, the REF1004I-1.2/2K5 is a voltage reference, not a voltage regulator. It's designed to provide a stable voltage reference, not to regulate voltage. Using it as a voltage regulator may lead to instability and inaccurate output.
  • The output impedance of the REF1004I-1.2/2K5 can be calculated using the equation: Zout = (ΔVout / ΔIout) || R_out, where R_out is the output resistance specified in the datasheet (typically around 10 ohms).
