Abstract (en)
[origin: EP0651309A2] A voltage regulator for regulating the voltage at a predetermined node connected to the core of a semiconductor device comprising reference voltage means for generating a reference voltage, an op-amp having said reference voltage as its reference input and the voltage at said predetermined node as its another input for adjusting the node voltage to match said reference voltage, series dropping means for supplying current load to the core, and filter capacitor coupled to said series dropping means for supplying transient current to said predetermined node. <IMAGE>
