Chapter 23 Voltage Regulator (S12VREGL3V3V1)
23.4
23.4.1
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)and a high temperature sensor (HTD).
23.4.2
Respectively its regulator core has three parallel, independent regulation loops (REG1,REG2 and REG3).
REG1 and REG3 differ only in the amount of current that can be delivered.
The regulators are linear regulator with a bandgap reference when operated in Full Performance Mode.
They act as a voltage clamp in Reduced Power Mode. All load currents flow from input VDDR to VSS or
VSSPLL. The reference circuits are supplied by VDDA and VSSA.
23.4.2.1
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.
23.4.2.2
In Reduced Power Mode, the gate of the output transistor is connected directly to a reference voltage to
reduce power consumption. Mode switching from reduced power to full performance requires a transition
time of t
23.4.3
Subblock LVD is responsible for generating the low-voltage interrupt (LVI). LVD monitors the input
voltage (V
status flag LVDS changes its value. The LVD is available in FPM and is inactive in Reduced Power Mode
or Shutdown Mode.
