11 Power Supply Recommendations

These devices are designed to operate from a 5 V input voltage supply. This input should be well regulated. If the input supply is located more than a few inches away from the TPD3S0x4, additional bulk capacitance may be required in addition to the recommended minimum 0.1 µF bypass capacitor on the IN pin to keep the input rail stable during fault events.
