LP3891EMRX-1.2/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stable and accurate output voltage, make sure to use a stable input voltage, decouple the input and output with capacitors, and use a low-ESR output capacitor.
  • The minimum input voltage required is 6.5V, but it's recommended to keep it above 7V for reliable operation.
  • The LP3891EMRX-1.2/NOPB is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
  • Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the device from input voltage transients.
