LP3875EMPX-ADJ/NOPB datasheet by Texas Instruments

LP3875EMPX-ADJ/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LP3875 can handle?
  The LP3875 can handle a maximum input voltage of 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
• How do I adjust the output voltage of the LP3875?
  The output voltage of the LP3875 can be adjusted by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
• What is the minimum input voltage required for the LP3875 to operate?
  The LP3875 requires a minimum input voltage of 2.5V to operate, but it's recommended to keep it above 3V for optimal performance.
• Can I use the LP3875 in a high-temperature environment?
  The LP3875 is rated for operation up to 125°C, but it's recommended to keep it below 85°C for optimal performance and to prevent overheating.
• How do I ensure the stability of the LP3875 output voltage?
  To ensure stability, it's recommended to use a minimum output capacitance of 10uF and to keep the output voltage within the recommended range of 1.2V to 12V.
