Voltage Regulator Circuits
The function of the internal Voltage Regulator circuits is to determine liquid crystal operating voltage, VOUT, by
adjusting resistors, Ra and Rb. Because VOUT is the operating voltage of operational-amplifier circuits shown in
Figure 21, it is necessary to be applied internally.
For the Eq. 1, we determine VOUT by Ra, Rb and V
EV
. The Ra and Rb are connected internally. 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
