A recommended PCB layout for optimal thermal performance would be to have a solid ground plane on the bottom layer, and to use thermal vias to connect the exposed pad to the ground plane. This helps to dissipate heat efficiently.
To ensure stable output voltage regulation, it is recommended to use a minimum output capacitance of 10uF, and to ensure that the output capacitor has a low ESR (Equivalent Series Resistance) to minimize voltage ripple.
Although the datasheet specifies a maximum input voltage of 18V, it is recommended to limit the input voltage to 15V to ensure reliable operation and to prevent damage to the device.
While the AP2511M8-13 is rated for operation up to 125°C, it is recommended to derate the output current and input voltage at high temperatures to ensure reliable operation and to prevent thermal shutdown.
The power dissipation of the AP2511M8-13 can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
