LMZ31710RVQR datasheet by Texas Instruments

LMZ31710RVQR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LMZ31710RVQR can handle?
  The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the LMZ31710RVQR is stable and doesn't oscillate?
  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.
• What is the minimum input voltage required for the LMZ31710RVQR to operate?
  The minimum input voltage is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the LMZ31710RVQR in a high-temperature environment?
  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.
• How do I calculate the output voltage of the LMZ31710RVQR?
  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.
