AP2128K-1.8TRG1 datasheet by Diodes Incorporated

AP2128K-1.8TRG1 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  For optimal thermal performance, it is recommended to have a solid ground plane on the bottom layer of the PCB, and to use thermal vias to connect the ground plane to the thermal pad of the AP2128K-1.8TRG1. Additionally, keep the PCB traces away from the thermal pad to minimize thermal resistance.
• How do I ensure stable output voltage regulation?
  To ensure stable output voltage regulation, make sure to decouple the input and output pins with suitable capacitors, and to use a stable input voltage source. Also, ensure that the output capacitor is of sufficient value and has a low ESR to maintain stability.
• What is the maximum ambient temperature for reliable operation?
  The AP2128K-1.8TRG1 is rated for operation up to 125°C ambient temperature. However, for reliable operation, it is recommended to keep the ambient temperature below 105°C to ensure a sufficient margin for thermal derating.
• Can I use this regulator in a high-current application?
  The AP2128K-1.8TRG1 is rated for a maximum output current of 2A. While it can handle high-current applications, it is essential to ensure that the PCB layout and thermal design can handle the heat generated by the regulator. Additionally, consider using a heat sink or thermal interface material to improve thermal performance.
• Is the AP2128K-1.8TRG1 compatible with lead-free soldering processes?
  Yes, the AP2128K-1.8TRG1 is compatible with lead-free soldering processes. Diodes Incorporated ensures that their products meet the requirements of the RoHS directive and are compatible with lead-free soldering processes.
