2.2 Power Supply
The power supply circuit consists of the input-stage and three voltage-regulators. The regulators are
switch-mode types (step-down).
Having the enables of the lower voltage supplies tied to the next higher voltage supply guarantees
correct sequencing in the order required (5V0 → 3V3 → 1V2). Power-down/disconnect of power-
domains and/or -rails is not supported.
All regulators are supplied from the input-rail Vin_prot (filtered input voltage, no regulator-staggering).
