🔧 Application Guidelines
Design Considerations
When designing with the AAT1117, it is essential to consider the input and output capacitors to ensure stability and optimal performance. The input capacitor should be placed as close as possible to the input pin, and the output capacitor should be selected based on the desired output voltage and load current.
Installation Guidelines
The AAT1117 should be mounted on a heat sink or a thermally conductive PCB to ensure proper heat dissipation. The device should be handled with care to avoid damage to the pins or the package.
Operational Notes
The AAT1117 is a linear regulator and should not be used in applications where high efficiency is required. The device is suitable for low to medium current applications and should not be used in high current applications without proper heat sinking.
