Abstract:
1. A voltage regulating circuit comprising: a control transistor at least partially formed in an n-type substrate; a regulating circuit comprising a regulating output coupled to a control region of the control transistor, wherein the regulating circuit comprises at least one transistor which is formed at least one of on and in the n-type substrate; an input terminal coupled to a first controlled terminal of the control transistor; wherein the first controlled terminal of the control transistor is provided over a first side of the n-type substrate; an output terminal coupled to a second controlled terminal of the control transistor; a layer provided on the first side of the n-type substrate, wherein the first controlled terminal of the control transistor is formed at a surface of the layer, and wherein the layer comprises an epitaxial layer.
