LM25122QPWPTQ1 Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the LM25122QPWPTQ1 is -40°C to 125°C.
  • To ensure stability, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1Ω or less, and to place the capacitor close to the output pin.
  • The recommended input capacitor value is 10uF to 22uF, with an ESR of 1Ω or less, and a voltage rating of 6.3V or higher.
  • The output voltage can be calculated using the formula: Vout = (R1/R2) * (1 + R3/R4) * Vref, where R1, R2, R3, and R4 are the resistors in the feedback network, and Vref is the internal reference voltage.
  • The maximum current rating for the LM25122QPWPTQ1 is 2A.
