R1171S421B-E2-FE Frequently Asked Questions (FAQs)

  • A 1-10uF ceramic capacitor with an ESR of 1Ω or less is recommended for input decoupling, placed as close to the VIN pin as possible.
  • Use a 1-10uF ceramic capacitor with an ESR of 1Ω or less for output decoupling, and ensure the output voltage is measured at the output pin of the IC, not at the load.
  • The maximum allowable ripple voltage is 1Vp-p, but it's recommended to keep it below 0.5Vp-p for stable operation.
  • The R1171S421B-E2-FE is rated for operation up to 125°C, but the output current may need to be derated for high-temperature operation. Consult the datasheet for specific derating curves.
  • Power dissipation can be calculated using the formula: Pd = (VIN - VOUT) x IOUT + VIN x IQ, where IQ is the quiescent current. Ensure the IC is properly heatsinked to prevent overheating.
