The TPSY227M004R0050: 50 mOhm ESR at 100 kHz typical means this cap handles ripple current without cooking itself — a switching regulator output sees less self-heating than a higher-ESR part would. ±20% tolerance is standard for tantalum capacitors — the actual capacitance at 25°C and 0 VDC bias sits between 176 µF and 264 µF. Under DC bias the capacitance drops about 20% at rated voltage, so budget the effective capacitance for your hold-up time calculation.
