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 TPS79930DDCRG4 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 3.3V output, the tolerance would be ±66mV).
The maximum input voltage of the TPS79930DDCRG4 is 15V, but it's recommended to operate the device within the specified input voltage range (5.5V to 12V) to ensure optimal performance and reliability.
To ensure stability of the output voltage, it's recommended to use a minimum output capacitance of 2.2μF, with an ESR of 0.1Ω to 10Ω. Additionally, the input capacitance should be at least 1μF, with an ESR of 0.1Ω to 10Ω.
The thermal shutdown temperature of the TPS79930DDCRG4 is typically around 150°C to 160°C, but this can vary depending on the specific device and operating conditions.
