Abstract
A voltage regulation circuit is suitable to provide an output voltage to a core circuit. The voltage regulation circuit includes a pad, a pull-low unit, a first controlling unit, a second controlling unit and a voltage regulation circuit. The pad receives and provides an input voltage. The pull-low unit generates a pull-low voltage according to the input voltage. The first controlling unit generates a first controlling signal according to the input voltage and the pull-low voltage. The second controlling unit generates a second controlling signal according to the input voltage and the first controlling signal. The voltage regulation unit regulates the input voltage according to the first controlling signal and the second controlling signal, so as to generate the output voltage.
