LP3871EMP-2.5/NOPB datasheet by Texas Instruments

LP3871EMP-2.5/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LP3871EMP-2.5/NOPB can handle?
  The maximum input voltage that the LP3871EMP-2.5/NOPB can handle is 15V. Exceeding this voltage may damage the device.
• How do I ensure the stability of the output voltage?
  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 output capacitor should be placed as close to the output pin as possible.
• What is the minimum input voltage required for the LP3871EMP-2.5/NOPB to operate?
  The minimum input voltage required for the LP3871EMP-2.5/NOPB to operate is 2.5V. The device will not operate correctly if the input voltage is below this threshold.
• Can I use the LP3871EMP-2.5/NOPB in a high-temperature environment?
  The LP3871EMP-2.5/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.
• How do I calculate the output voltage tolerance?
  The output voltage tolerance can be calculated by adding the initial voltage tolerance (±2%) to the temperature coefficient (±0.02%/°C) multiplied by the operating temperature range. For example, if the operating temperature range is 0°C to 85°C, the output voltage tolerance would be ±2% ± (0.02%/°C x 85°C) = ±4.7%.
