LM25149RGYR Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the LM25149RGYR is -40°C to 125°C.
  • 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.
  • The maximum input voltage that the LM25149RGYR can handle is 42V.
  • Yes, the LM25149RGYR is designed to handle high currents up to 5A, but it's recommended to use a heat sink to ensure proper thermal management.
  • The output voltage of the LM25149RGYR can be calculated using the formula: Vout = (R1/R2) * (Vin - Vref), where R1 and R2 are the resistors in the feedback network, Vin is the input voltage, and Vref is the reference voltage.
