Title:
LOW-DROPOUT REGULATORS
Document Type and Number:
WIPO Patent Application WO/2018/161834
Kind Code:
A1
Abstract:
A low-dropout regulator (100) comprises a first switching transistor (104), a comparator (102), and a Miller capacitor (106). The first terminal of the first switching transistor (104) is connected to a load (108), and the second terminal of the first switching transistor (104) is connected to a power supply voltage. The first input terminal of the comparator (102) is connected to a reference voltage (Vref), the second input terminal of the comparator (102) is connected to the first terminal of the first switching transistor (104), and the output terminal of the comparator (102) is connected to the control terminal of the first switching transistor (104). The first terminal of the Miller capacitor (106) is connected to the control terminal of the first switching transistor (104), and the second terminal of the Miller capacitor (106) is connected to the first terminal of the first switching transistor (104) and the load (108).
