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 TPS79601DRBTG4 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 1.8V output, the tolerance would be ±36mV (1.8V x 0.02).
The absolute maximum input voltage rating for the TPS79601DRBTG4 is 6.5V. Applying a voltage higher than this can damage the device. 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 output capacitor has a low ESR (Equivalent Series Resistance). Additionally, keep the input and output capacitors close to the device, and use a solid ground plane to reduce noise and EMI.
The quiescent current of the TPS79601DRBTG4 is typically around 20μA. This current is consumed by the device even when the output is not loaded. To minimize power consumption, consider using a low-quiescent-current LDO regulator or implementing power-saving features such as shutdown or low-power modes.
