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 TPS75801KTTRG3 is specified as ±2% over the operating temperature range. To calculate the output voltage tolerance, multiply the nominal output voltage by the tolerance percentage. For example, for a 3.3V output, the tolerance would be ±66mV.
The maximum input voltage of the TPS75801KTTRG3 is 15V, but it's recommended to operate the device within the specified input voltage range of 3.5V to 12V to ensure optimal performance and reliability.
The TPS75801KTTRG3 is designed to regulate the output voltage during input voltage transients, but it's recommended to add input capacitors to filter out high-frequency noise and ensure stable operation. The device also has a built-in undervoltage lockout (UVLO) feature that disables the output during input voltage drops.
The thermal shutdown temperature of the TPS75801KTTRG3 is typically around 150°C to 160°C, but it's recommended to consult the datasheet for the specific device and to implement thermal management techniques to prevent overheating.
