AS7815ADTR-G1 datasheet by Diodes Incorporated

AS7815ADTR-G1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  A thermal pad is recommended under the package to improve heat dissipation. A minimum of 2oz copper thickness and a thermal relief pattern are also recommended.
• How do I ensure stable output voltage regulation?
  Ensure that the input voltage is within the recommended range, and that the output capacitor is of sufficient value (at least 10uF) and ESR (less than 1 ohm) to maintain stability.
• What is the maximum ambient temperature for reliable operation?
  The maximum ambient temperature for reliable operation is 85°C, with a maximum junction temperature of 125°C.
• Can I use this regulator in a high-current application?
  Yes, but ensure that the input voltage is sufficient to support the output current, and that the thermal design is adequate to dissipate the heat generated.
• How do I protect the regulator from input voltage transients?
  Use a TVS diode or a transient voltage suppressor in parallel with the input capacitor to protect the regulator from input voltage transients.
