LP3871EMP-1.8/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LP3871EMP-1.8/NOPB is 15V. Exceeding this voltage can cause damage to the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the input capacitor should be at least 1uF with an ESR of less than 1 ohm.
  • The thermal shutdown temperature of the LP3871EMP-1.8/NOPB is typically around 150°C. When the junction temperature exceeds this value, the device will shut down to prevent damage.
  • The LP3871EMP-1.8/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the output current and voltage according to the temperature derating curve in the datasheet.
  • The output voltage tolerance of the LP3871EMP-1.8/NOPB is typically ±2%. This means that the output voltage can vary by up to 2% of the nominal output voltage (1.8V) due to manufacturing variations and operating conditions.
