LP3891EMRX-1.2/NOPB datasheet by Texas Instruments

LP3891EMRX-1.2/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3891EMRX-1.2/NOPB?
  The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the output voltage is stable and accurate?
  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.
• What is the minimum input voltage required for the LP3891EMRX-1.2/NOPB to operate?
  The minimum input voltage required is 6.5V, but it's recommended to keep it above 7V for reliable operation.
• Can I use the LP3891EMRX-1.2/NOPB in a high-temperature environment?
  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.
• How do I protect the LP3891EMRX-1.2/NOPB from input voltage transients?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the device from input voltage transients.
