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 TPS70302PWPRG4 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 that can be applied to the TPS70302PWPRG4 is 15V, but it's recommended to limit the input voltage to 12V to ensure reliable operation and to prevent damage to the device.
The TPS70302PWPRG4 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to ensure reliable operation. Consult the datasheet for specific derating guidelines.
To ensure stability, follow the recommended capacitor values and types in the datasheet, and keep the input and output capacitors close to the device. Additionally, ensure that the PCB layout is well-designed and that the device is properly decoupled from the power source.
