🔧 Application Guidelines
Design Considerations
The AAT3239 is designed for low input voltage and low power consumption applications. 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 PCB with adequate thermal dissipation. The input and output capacitors should be placed as close as possible to the device.
Operational Notes
The device has built-in thermal shutdown and current limit protection. However, it is still important to ensure that the device is not subjected to excessive heat or overcurrent conditions.
