Abstract
A voltage regulation device includes a first transistor, a first bias current source, a bias resistor, a second transistor, a second bias current source, and a detection adjustment circuit. The first transistor is coupled to the first bias current source for outputting a reference voltage. The bias resistor is coupled to the first transistor for receiving a regulation current. The second transistor has a first terminal for receiving a system voltage, a second terminal for outputting an output voltage, and a control terminal for receiving the reference voltage. The second bias current source is coupled to the second terminal of the second transistor. The detection adjustment circuit is coupled to the first transistor and the second transistor. When the output voltage is too low, the detection adjustment circuit activates the compensation current source to increase the voltage at the control terminal of the second transistor.
