This kind of adjustment voltage and the metal line above the protective layer or the design of the surface transmission voltage can be accurately controlled to the internal circuit and accurately controlled at the - voltage level. In addition, the output voltage of the voltage regulator is between the positive and negative 10% of the target county in the voltage regulator (that is, the voltage difference between the voltage value and the slave target voltage value).

Continuing, the reference voltage Vr can be regulated by the connection of the drain of the P-type MOS transistor 4103 to the gate of the p-type MOS transistor 4104. Therefore, when the external power supply voltage Vdd fluctuates, the voltage of the node 上升 rises, resulting in a lower degree of opening of the p-type MOS transistor 4104, which in turn causes the reference voltage Vr to drop.
