Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for low-noise, high-precision analog circuit design, such as separating analog and digital grounds, using a solid ground plane, and minimizing trace lengths and widths.
To ensure stability, make sure to follow the recommended capacitor values and types for the input and output pins, and avoid using capacitors with high equivalent series resistance (ESR). Additionally, ensure that the output is properly decoupled and that the input voltage is within the recommended range.
While the datasheet specifies a maximum input voltage of 15V, it's recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the device.
The TLV1171-15DCYR is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage according to the temperature derating curve provided in the datasheet.
Start by verifying that the input voltage and output load are within the recommended specifications. Check for proper PCB layout, decoupling, and grounding. Use an oscilloscope to measure the output voltage and input voltage ripple. If issues persist, consult the datasheet and application notes for troubleshooting guidelines.
