LM25145RGYR Frequently Asked Questions (FAQs)

  • The LM25145RGYR can handle input voltages up to 42V, but it's recommended to keep it below 40V for optimal performance and reliability.
  • To prevent overheating, ensure good airflow, use a heat sink if necessary, and keep the device within its recommended operating temperature range of -40°C to 125°C.
  • The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stable operation.
  • While the LM25145RGYR can operate up to 125°C, it's not recommended for use in extremely high-temperature environments. Consider using a heat sink or a thermally-enhanced package if operating above 85°C.
  • To optimize the output voltage, adjust the feedback resistors (R1 and R2) to achieve the desired output voltage. Ensure the resistors are within the recommended range (1kΩ to 100kΩ) for stable operation.
