Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency PCB design guidelines, such as using a solid ground plane, minimizing trace lengths, and using decoupling capacitors close to the device.
To ensure stability, follow the recommended compensation network values and layout, and ensure that the output capacitor is properly sized and placed. Additionally, minimize the distance between the device and the output capacitor, and use a low-ESR capacitor.
The maximum input voltage is 15V, but it's recommended to operate the device within the specified input voltage range (2.7V to 5.5V) to ensure optimal performance and reliability.
The LMS8117AMP-3.3 is rated for operation up to 125°C, but it's recommended to derate the output current and ensure proper thermal management to prevent overheating and ensure reliability.
Use a oscilloscope to monitor the output voltage and current, and check for proper input voltage, decoupling, and compensation network values. Also, ensure that the device is properly soldered and that there are no layout or manufacturing defects.
