A capacitor structure is provided. The capacitor structure is configured in a substrate. The capacitor structure includes a plurality of electrode sets, at least a first conductive plug and at least a second conductive plug. The electrode sets correspond with each other and are disposed in different layers of the substrate. Each electrode set comprises a first electrode and a second electrode surrounding the former. In addition, the first conductive plug and the second conductive plug are disposed between two adjacent electrode sets. First electrodes of two adjacent electrode sets correspond with each other and are electrically connected to each other through the first conductive plug. Similarly, second electrodes of two adjacent electrode sets correspond with each other and are electrically connected to each other through the second conductive plug.

A voltage regulator apparatus, wherein two transistors are coupled to an output terminal of a voltage regulator, so as to improve the transient response of output voltage and increase the stability of the output voltage. Besides, it avoids the use of an external capacitor.

Voltage regulator apparatus

A voltage regulator, regulating a supply voltage and outputting a regulated voltage. The voltage regulator comprises a two stage OP which outputs a first voltage and a second voltage according to a reference voltage and a feedback voltage. A NMOS transistor controlled by a voltage detection unit, to receive the second voltage when the detected supply voltage is in a high mode. A PMOS transistor controlled by the voltage detection unit, to receive the first voltage when the detected supply voltage is in a low mode. A feedback circuit for receiving the regulated voltage and outputting the feedback voltage to the two stage OP.
