DB2731400L datasheet by Panasonic Electronic Components

DB2731400L Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A thermal pad on the bottom of the device should be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
• How do I ensure reliable operation in high-humidity environments?
  Apply a conformal coating to the device and PCB to protect against moisture. Ensure the coating is compatible with the device's materials and follows the manufacturer's guidelines.
• What is the maximum allowed voltage on the input pins?
  The maximum allowed voltage on the input pins is 5.5V, exceeding which may cause damage to the device. Ensure proper voltage regulation and protection circuits are in place.
• Can I use the DB2731400L in a battery-powered device?
  Yes, the DB2731400L is suitable for battery-powered devices due to its low quiescent current (IQ) of 1.5mA. However, consider the device's power consumption and battery life requirements.
• How do I troubleshoot issues with the device's output voltage?
  Check the input voltage, output load, and PCB layout for any issues. Verify the device is properly soldered and the output capacitor is of sufficient value and type.
