🔧 Application Guidelines
Design Considerations
The AAT3223 is designed for use in handheld devices and other portable electronics. It is recommended to use a 1μF ceramic capacitor at the input and a 2.2μF ceramic capacitor at the output for stability.
Installation Guidelines
The device should be mounted on a printed circuit board with adequate thermal dissipation. The input and output capacitors should be placed as close as possible to the device.
Operational Notes
The device has a thermal shutdown protection feature that will turn off the output if the junction temperature exceeds 150°C. The device will automatically recover when the junction temperature drops below 120°C.
