S-80845CLNB-B66T2U Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ABLIC recommends a thermal pad on the bottom of the package, connected to a copper plane on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
• How do I ensure stable output voltage during startup and shutdown?
  To ensure stable output voltage, add a 1uF ceramic capacitor between the VIN and GND pins, and a 10uF electrolytic capacitor between the VOUT and GND pins. This will help filter out noise and reduce voltage droop during startup and shutdown.
• What is the maximum allowed input voltage ripple for this regulator?
  The maximum allowed input voltage ripple is 10% of the input voltage. Exceeding this may affect the regulator's stability and output voltage accuracy.
• Can I use this regulator in a high-temperature environment?
  The S-80845CLNB-B66T2U is rated for operation up to 125°C. However, derating the output current is recommended for temperatures above 85°C to ensure reliable operation.
• How do I protect the regulator from overcurrent and short-circuit conditions?
  The S-80845CLNB-B66T2U has built-in overcurrent protection (OCP) and short-circuit protection (SCP). However, adding an external fuse or PTC thermistor can provide additional protection against overcurrent and short-circuit conditions.
