LP3891EMR-1.2 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP3891EMR-1.2 is 15V, but it's recommended to keep it below 13.2V to ensure reliable operation.
  • To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and add a 10nF capacitor between the VIN and GND pins.
  • The minimum input voltage required for the LP3891EMR-1.2 to operate is 2.5V, but it's recommended to keep it above 2.7V for reliable startup and operation.
  • The LP3891EMR-1.2 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at higher temperatures to ensure reliable operation.
  • The output voltage of the LP3891EMR-1.2 can be calculated using the formula: VOUT = 1.2V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin.
