STMicroelectronics recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
To ensure reliable operation in high-temperature environments, it is recommended to derate the device's power dissipation according to the temperature derating curve provided in the datasheet, and to ensure good thermal conduction between the device and the PCB.
STMicroelectronics recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, depending on the specific application requirements, to ensure optimal performance and stability.
To troubleshoot issues with the device's output voltage regulation, check the input voltage, output load, and feedback loop components, and ensure that the device is properly configured and compensated according to the datasheet recommendations.
STMicroelectronics recommends using a pi-filter configuration with a ferrite bead and capacitors to minimize EMI emissions, and to follow good PCB layout practices such as separating analog and digital grounds and using a solid ground plane.
