POWER SUPPLY CIRCUITS
The Power Supply circuits generate the voltage levels necessary to drive liquid crystal driver circuits with low power
consumption and the fewest components. There are voltage converter circuits, voltage regulator circuits, and voltage
follower circuits. They are controlled by power control instruction. For details, refers to "Instruction Description". Table 4
shows the referenced combinations in using Power Supply circuits.
