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 vias to connect the input and output capacitors to the ground plane.
To ensure stability, follow the recommended component values and PCB layout, and make sure the input and output capacitors are properly selected and placed. Additionally, the datasheet provides a stability analysis section that can help you determine the stability of the device.
The maximum input voltage is not explicitly stated in the datasheet, but it's recommended to follow the absolute maximum ratings section, which specifies a maximum input voltage of 42V. However, it's recommended to operate the device within the recommended operating conditions for optimal performance and reliability.
The LM25101 is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to follow the recommended operating conditions and to consider the thermal design and heat dissipation of the system to ensure reliable operation.
The datasheet provides guidelines for selecting input and output capacitors, including the recommended capacitance values and equivalent series resistance (ESR). It's also important to consider the capacitor's voltage rating, temperature coefficient, and physical size when making a selection.
