LF85CDT-TRY Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN4566, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The input capacitor value depends on the input voltage, output voltage, and output current. A general rule of thumb is to choose a capacitor with a value between 1uF to 10uF, with a voltage rating at least 1.5 times the input voltage. Consult the datasheet and application notes for more specific guidance.
  • The LF85CDT-TRY is rated for operation up to 125°C ambient temperature, but it's recommended to derate the output current and voltage to ensure reliable operation above 85°C. Consult the datasheet for thermal derating curves and guidelines.
  • To ensure EMC compliance, follow the guidelines in the application note AN4566, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a metal shield or a ferrite bead on the output to reduce electromagnetic interference (EMI).
  • The output capacitor value and type depend on the output voltage, output current, and desired ripple voltage. A general rule of thumb is to choose a low-ESR capacitor with a value between 1uF to 10uF, with a voltage rating at least 1.5 times the output voltage. Consult the datasheet and application notes for more specific guidance.
