The TPS259271DRCR: The 5 A figure is the maximum continuous current the internal FET can pass at 25°C with adequate PCB copper; derate for ambient temperature and board area per the datasheet's SOA curve. For a 12 V rail pulling 4 A steady-state, this part leaves 1 A of headroom before the ±8% accuracy band starts to matter.
