Abstract

See full text

A voltage regulating apparatus is disclosed. The voltage regulating apparatus includes: a power transistor having a control terminal, a first terminal for receiving a power supply, and a second terminal for providing an output voltage; a feedback circuit coupled to the second terminal, configured for providing a feedback voltage according to the output voltage; an amplifier having a source current unit and a sink current unit, configured for driving the power transistor through the control terminal by use of the source and sink current units according to a reference voltage and the feedback voltage; and a transient enhancement unit configured for monitoring the source and sink current units, and regulating a voltage at the control terminal according to the monitored result.
