S-1313A15-M5T1U3 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 large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
• How do I ensure stability and prevent oscillation in the output voltage?
  To ensure stability, use a minimum output capacitance of 1uF with an ESR of 1Ω or less, and a ceramic capacitor with a voltage rating of 6.3V or higher. Additionally, keep the input and output capacitors close to the regulator.
• What is the maximum allowed voltage on the EN pin?
  The maximum allowed voltage on the EN pin is 6.0V. Exceeding this voltage may damage the internal circuitry.
• Can I use this regulator in a high-temperature environment?
  The S-1313A15-M5T1U3 is rated for operation up to 125°C. However, the output voltage may decrease at high temperatures due to the internal thermal protection circuit. Ensure the device is properly heatsinked and the output voltage is monitored.
• How do I calculate the power dissipation of the regulator?
  Power dissipation (PD) can be calculated using the formula: PD = (VIN - VOUT) x IOUT. Ensure the calculated PD is within the maximum rating of 1.5W.
