14.4.1
Module VREG_3V3 is a voltage regulator, as depicted in
are the regulator core (REG), a low-voltage detect module (LVD), a control block (CTRL), a power-on
reset module (POR), and a low-voltage reset module (LVR).
14.4.2
Respectively its regulator core has two parallel, independent regulation loops (REG1 and REG2) that differ
only in the amount of current that can be delivered.
The regulator is a linear regulator with a bandgap reference when operated in Full Performance Mode. It
acts as a voltage clamp in Reduced Power Mode. All load currents flow from input V
V
14.4.2.1
In Full Performance Mode, the output voltage is compared with a reference voltage by an operational
amplifier. The amplified input voltage difference drives the gate of an output transistor.
