PD85035S-E datasheet by STMicroelectronics

PD85035S-E Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  STMicroelectronics recommends a 2-layer or 4-layer PCB with a solid ground plane and a thermal relief pattern around the device to ensure optimal thermal performance.
• How do I ensure reliable operation in high-temperature environments?
  To ensure reliable operation in high-temperature environments, ensure proper heat sinking, use a thermal interface material, and follow the recommended PCB layout guidelines. Additionally, consider using a thermal shield or heat sink to reduce the junction temperature.
• What is the maximum allowed voltage on the input pins?
  The maximum allowed voltage on the input pins is 6.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
• Can I use the PD85035S-E in a battery-powered application?
  Yes, the PD85035S-E is suitable for battery-powered applications due to its low quiescent current and high efficiency. However, ensure proper power management and consider using a low-dropout regulator to minimize power consumption.
• How do I troubleshoot issues with the device not turning on or not regulating properly?
  To troubleshoot issues, check the input voltage, output voltage, and enable pin voltage. Verify that the input voltage is within the recommended range, and the enable pin is properly biased. Also, check for any short circuits or incorrect component values.
