The internal Voltage Reference is set at 1.210 V (bandgap reference). The voltage control loop precision

takes into account the cumulative effects of the internal voltage reference deviation as well as the input

offset voltage of the trans-conductance operational amplifier. The internal Voltage Reference is fixed by

bandgap, and trimmed to 0.5 % accuracy at room temperature.
