Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines 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.
The output capacitor value depends on the specific application and desired output voltage ripple. A general rule of thumb is to choose a capacitor with a value between 1uF to 10uF, with a voltage rating that exceeds the output voltage. TI also provides a capacitor selection guide in the datasheet.
The TLV76790QWDRBRQ1 has an absolute maximum input voltage rating of 6V. Exceeding this voltage can damage the device. However, the recommended operating input voltage range is 2.7V to 5.5V.
The TLV76790QWDRBRQ1 is rated for operation up to 125°C. However, the device's performance and accuracy may degrade at higher temperatures. It's recommended to follow the thermal design guidelines in the datasheet and to consider using thermal management techniques, such as heat sinks or thermal interfaces, to maintain a safe operating temperature.
To ensure EMC, follow proper PCB design and layout practices, such as using a solid ground plane, minimizing trace lengths and widths, and using shielding or filtering components as needed. Additionally, ensure that the device is properly decoupled and that the input and output pins are properly terminated.
