Voltage Regulator (S12VREGL3V3V1)
23.1
Module VREG_3V3 is a tri output voltage regulator that provides two separate 1.84V (typical) supplies
differing in the amount of current that can be sourced and a 2.82V (typical) supply. The regulator input
voltage range is from 3.3V up to 5V (typical).
23.1.1
Module VREG_3V3 includes these distinctive features:
23.1.2
There are three modes VREG_3V3 can operate in:

1. Full performance mode (FPM) (MCU is not in stop mode)
2. Reduced power mode (RPM) (MCU is in stop mode)
Three parallel, linear voltage regulators with bandgap reference
Low-voltage detect (LVD) with low-voltage interrupt (LVI)
Power-on reset (POR)
Low-voltage reset (LVR)
High Temperature Detect (HTD) with High Temperature Interrupt (HTI)
Autonomous periodical interrupt (API)
The regulator is active, providing the nominal supply voltages with full current sourcing capability.
Features LVD (low-voltage detect), LVR (low-voltage reset), and POR (power-on reset) and HTD
(High Temperature Detect) are available. The API is available.
The purpose is to reduce power consumption of the device. The output voltage may degrade to a
lower value than in full performance mode, additionally the current sourcing capability is
substantially reduced. Only the POR is available in this mode, LVD, LVR and HTD are disabled.
The API is available.
