Voltage Regulator Circuits
The function of the internal Voltage Regulator circuits is to determine liquid crystal operating voltage, V0, by
adjusting resistors, Ra and Rb, within the range of |V0| < |VOUT|. Because VOUT is the operating voltage of
operational-amplifier circuits shown in figure 20, it is necessary to be applied internally or externally.
For the Eq. 1, we determine V0 by Ra, Rb and V
EV
. The Ra and Rb are connected internally or externally by INTRS
pin. And V
EV
called the voltage of electronic volume is determined by Eq. 2, where the parameter
α
is the value
selected by instruction, "Set Reference Voltage Register", within the range 0 to 63. V
