LP3990MF-1.8 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP3990MF-1.8 is 12V, but it's recommended to keep it below 10V for optimal performance and to prevent overheating.
  • To ensure stability, make sure to follow the recommended PCB layout and component placement guidelines, use a sufficient output capacitor (at least 10uF), and keep the input voltage ripple below 100mV.
  • The minimum input voltage required for the LP3990MF-1.8 to operate is 2.5V, but it's recommended to keep it above 2.7V for optimal performance.
  • The LP3990MF-1.8 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to prevent overheating and ensure reliability.
  • The output voltage tolerance of the LP3990MF-1.8 is typically ±2% over the operating temperature range, but it can be affected by factors such as input voltage, output current, and temperature. Consult the datasheet for more information.
