ON-CHIP VOLTAGE REGULATOR
The BCM2035 has a full integrated on-chip voltage regulator. The on-chip regulator operates from a 3.3V
supply and can generate a 1.8V regulated supply. The on chip regulator can be selectively enabled or disabled
via the REG_CTRL pin.
Figure 15 shows the configuration with the internal regulator enabled.
