Abstract
A circuit arrangement for voltage regulation including a first transistor coupled between a first node and a third node, a second transistor coupled between a second node and the third node, a third transistor coupled between the third node and an output node, and a control unit that can be coupled to the first transistor, that can be coupled to the second transistor, and is coupled to the third transistor, wherein the control unit is configured to steer the transistors such that a predetermined output voltage is provided at the output node when a supply voltage is provided at one of the first node and the second node.
