1.3 VOLTAGE REGULATOR
The internal Voltage Regulator (VR) is used to
power the microcontroller starting from the exter-
nal power supply. The VR comprises a Main volt-
age regulator and a Low-power regulator.
– The Main voltage regulator generates sufficient
– The separate Low-Power regulator consumes
