LMZ21701SILT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power lines.
  • Ensure the output capacitor has a low ESR, and the input capacitor is at least 10uF. Also, add a 10nF capacitor between the VIN and GND pins to filter out noise.
  • The maximum input voltage is 17V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • The LMZ21701SILT is rated for operation up to 125°C, but the maximum junction temperature is 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
  • Use the formula: Vout = (R1/R2) * (VIN - Vdropout), where R1 and R2 are the feedback resistors. The maximum output current is 1A, but it's recommended to derate to 0.8A for optimal performance.
