The TPSC227M006Y0125: 220 µF capacitance at 6.3 V rated voltage gives this TPS-series tantalum enough charge storage to smooth a 3.3 V or 1.8 V rail's ripple during load transients. The 125 mOhm ESR limits the ripple voltage at the switching frequency — for a 1 A peak-to-peak ripple current, the voltage ripple is 125 mV, which keeps most digital loads within their supply tolerance.
