LDL112PU18R Frequently Asked Questions (FAQs)

  • STMicroelectronics provides a recommended PCB layout in the application note AN2669, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
  • The output capacitor value depends on the specific application requirements, such as output voltage ripple, transient response, and stability. A general guideline is to use a capacitor with a value between 10uF to 100uF, with a voltage rating of at least 1.5 times the output voltage. Consult the application note AN2669 for more detailed guidance.
  • The LDL112PU18R is rated for operation up to 150°C ambient temperature, but it's recommended to derate the output current and voltage to ensure reliable operation above 125°C. Consult the datasheet and application note AN2669 for thermal management guidelines.
  • To ensure EMC compliance, follow the guidelines in the application note AN2669, which includes recommendations for PCB layout, component selection, and shielding. Additionally, consider using a metal shield or a mu-metal shield around the LDL112PU18R to reduce radiated emissions.
  • A ceramic or film capacitor with a value between 1uF to 10uF is recommended for the input capacitor. The capacitor should be rated for the input voltage and have a low equivalent series resistance (ESR) to minimize input voltage ripple and ensure stable operation.
