Abstract
A voltage generator circuit uses a feedback loop to regulate an output voltage at an output node. A pair of opposite conductivity source-follower transistors are coupled to the output node. A first one of the source-follower transistors operates to provide a fast current transient for charging a capacitive load that is switchably connected to the output node. A second one of the source-follower transistor operate under feedback control to regulate the voltage level at the output node.
