Abstract
The invention provides a voltage regulator including a transient voltage suppressor. The transient voltage suppressor includes N first transistors and N semiconductor units. The N first transistors are coupled between a reference ground and N pads respectively, and the N transistors are controlled by a voltage on a reference power line. The N semiconductor units are coupled between the reference ground and the N pads respectively, or coupled between the reference power line and the N pads respectively. N is a positive integer.
