220 µF bulk decoupling with 100 mOhm ESR
The TPSD227K006H0100: This is a 220 µF molded tantalum capacitor rated at 6.3 V, with a maximum ESR of 100 mOhm. The 100 mOhm ESR keeps ripple current self-heating low and output voltage ripple tight on a 6.3 V rail — useful for post-regulator bulk decoupling where the downstream load draws fast transients.
