The ADP5037ACPZ-R7: The buck outputs are adjustable from 0.8 V to 3.8 V each, while the LDOs cover 0.8 V to 5.2 V — enough headroom to feed a 3.3 V digital core, a 1.8 V I/O bank, and a clean 2.5 V analog supply from one IC.
The two synchronous buck converters each deliver up to 800 mA, and the two LDOs each deliver up to 300 mA.
