AP7381-28SA-7 Frequently Asked Questions (FAQs)

The recommended PCB layout for optimal thermal performance involves placing the device on a thermal pad with a minimum size of 20mm x 20mm, and ensuring that the thermal pad is connected to a large copper area on the PCB to dissipate heat efficiently.
To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of less than 1 ohm, and to place the output capacitor close to the output pin of the device.
Although the datasheet specifies a maximum input voltage of 28V, it is recommended to limit the input voltage to 24V to ensure reliable operation and to prevent damage to the device.
The AP7381-28SA-7 has a built-in overcurrent protection feature that limits the output current to 3.5A. However, it is still recommended to add an external fuse or overcurrent protection circuit to prevent damage to the device and the PCB in case of a fault condition.
The recommended input capacitor value is 10uF to 22uF, and it is recommended to use a low-ESR ceramic capacitor such as X5R or X7R type to minimize input voltage ripple and ensure stable operation.
