Abstract:
A voltage regulator has a first charge circuit, a second charge circuit, and a control circuit. The control circuit has five input terminals and two output terminals. The five input terminals are respectively coupled to a reference voltage, a first voltage source, a second voltage source, an output terminal of the first charge circuit, and an output terminal of the second charge circuit. The control circuit equalizes a voltage difference between the output terminal of the first charge circuit and the first voltage source and a voltage difference between the second voltage source and the output terminal of the second charge circuit.
