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 to reduce noise and EMI.
The output voltage tolerance of the TPS75233QPWPRG4 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 voltage, the tolerance would be ±66mV.
The maximum input voltage that can be applied to the TPS75233QPWPRG4 is 15V, but it's recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the device.
To ensure stability, follow the recommended capacitor values and types in the datasheet, and make sure the output capacitor has a low ESR (Equivalent Series Resistance). Additionally, avoid using capacitors with high ESL (Equivalent Series Inductance) and ensure that the input and output capacitors are placed close to the device.
The thermal shutdown temperature of the TPS75233QPWPRG4 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.
