LP3875EMP-1.8/NOPB datasheet by Texas Instruments

LP3875EMP-1.8/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LP3875EMP-1.8/NOPB?
  The maximum input voltage that can be applied to the LP3875EMP-1.8/NOPB is 15V. Exceeding this voltage can cause damage to the device.
• How do I ensure the stability of the output voltage in my design?
  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 capacitance should be at least 1uF.
• What is the minimum input voltage required for the LP3875EMP-1.8/NOPB to operate?
  The minimum input voltage required for the LP3875EMP-1.8/NOPB to operate is 2.5V. However, the device can operate down to 2.2V with a reduced output current capability.
• Can I use the LP3875EMP-1.8/NOPB in a high-temperature environment?
  The LP3875EMP-1.8/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It is recommended to derate the output current and input voltage according to the temperature derating curve in the datasheet.
• How do I calculate the power dissipation of the LP3875EMP-1.8/NOPB?
  The power dissipation of the LP3875EMP-1.8/NOPB can be calculated using the formula: Pd = (Vin - Vout) x Iout + Vin x Iq, where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
