LMV431CZ/NOPB Frequently Asked Questions (FAQs)

  • The recommended operating temperature range for the LMV431CZ/NOPB is -40°C to 125°C. However, it's essential to note that the device's performance may vary outside the typical operating temperature range of 0°C to 70°C.
  • To ensure the stability of the voltage reference output, it's crucial to decouple the input pin (VCC) with a 0.1 μF ceramic capacitor and a 1 μF tantalum capacitor in parallel. Additionally, the output pin (VREF) should be decoupled with a 0.01 μF ceramic capacitor.
  • The minimum input voltage for the LMV431CZ/NOPB is 1.4 V, and the maximum input voltage is 18 V. Operating the device outside this range may affect its performance and accuracy.
  • No, the LMV431CZ/NOPB is not designed to be used as a voltage regulator. It's a voltage reference device, and its output current is limited to 10 mA. If you need a voltage regulator, consider using a dedicated voltage regulator IC, such as the LM317 or LM1117.
  • The voltage reference output of the LMV431CZ/NOPB has an initial accuracy of ±1.5% and a temperature coefficient of ±20 ppm/°C. This means that the output voltage can vary by up to ±1.5% of the nominal value (2.5 V) over the operating temperature range.
