Design Considerations & Integration

When integrating the AP7369Q-33E-13 into your design, consider these best practices:

• Use a minimum 1µF ceramic capacitor on the output for stability (10µF recommended for optimal transient response)
• Input bypass capacitor (1µF or greater) should be placed close to the device for best performance
• Ensure adequate PCB copper area for thermal management, especially at higher output currents
• The SOT-223 package provides excellent thermal performance with proper PCB layout
• Consider input voltage transients and add appropriate TVS protection for automotive applications
