LMZ31710RVQR Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, make sure to use the recommended output capacitor (10uF ceramic) and input capacitor (10uF ceramic or 22uF electrolytic) as close to the device as possible. Also, keep the input and output traces short and away from noise sources.
  • The minimum input voltage is 6.5V, but it's recommended to keep it above 7V for reliable operation.
  • The LMZ31710RVQR is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
  • The output voltage is set by the resistor divider network (R1 and R2) connected to the FB pin. Use the formula: Vout = 0.8V x (1 + R2/R1) to calculate the output voltage.
