LM51571QRTERQ1 Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the LM51571QRTERQ1 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 with an ESR of 10mΩ or less, and to place the capacitor as close to the output pin as possible.
  • The recommended input capacitor value for the LM51571QRTERQ1 is 10uF to 22uF, with an ESR of 10mΩ or less.
  • The output voltage of the LM51571QRTERQ1 can be calculated using the formula: Vout = (R1/R2) * (Vref), where R1 and R2 are the resistors connected to the FB pin, and Vref is the internal reference voltage (1.21V).
  • The maximum input voltage for the LM51571QRTERQ1 is 42V.
