LD39020ATPU185R Frequently Asked Questions (FAQ)

  • STMicroelectronics provides a recommended PCB layout in the application note AN5093, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.

  • The input capacitor selection depends on the input voltage, output voltage, and output current. A general guideline is to choose a capacitor with a voltage rating of at least 1.5 times the input voltage, and a capacitance value between 1uF to 10uF. Consult the application note AN5093 for more detailed guidance.

  • The maximum allowed voltage drop across the LD39020ATPU185R is 1.5V. Exceeding this voltage drop may affect the device's reliability and performance. Ensure that the input voltage is within the recommended range to maintain a safe voltage drop.

  • The LD39020ATPU185R is rated for operation up to 150°C. However, the device's performance and reliability may degrade at high temperatures. Consult the datasheet and application notes for thermal derating guidelines and ensure proper thermal management in your design.

  • Start by verifying the input voltage, output voltage, and output current are within the recommended ranges. Check the PCB layout for thermal issues, and ensure proper component selection and placement. Consult the application notes and STMicroelectronics' support resources for further guidance and troubleshooting techniques.
