Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for LDO regulator layout, such as keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing trace lengths and widths.
The output voltage tolerance of the TPS79618DCQG4 is specified as ±2% over the operating temperature range. To calculate the output voltage tolerance, multiply the nominal output voltage by the tolerance percentage (e.g., for a 1.8V output, the tolerance would be ±36mV).
The maximum input voltage that can be applied to the TPS79618DCQG4 is 6.5V, which is the absolute maximum rating. However, it's recommended to operate the device within the recommended input voltage range of 2.7V to 5.5V to ensure optimal performance and reliability.
To ensure stability, follow the recommended capacitor values and types in the datasheet, and make sure the input and output capacitors are placed close to the device. Additionally, avoid using capacitors with high equivalent series resistance (ESR) and ensure that the PCB layout is well-designed to minimize parasitic inductance and capacitance.
The thermal shutdown temperature of the TPS79618DCQG4 is typically around 150°C to 160°C, but this can vary depending on the specific device and operating conditions. Refer to the datasheet for more information.
