| description | The present invention relates to an electronic device including low-dropout (LDO) regulators, which produce output voltage with improved response and accuracy. The electronic device of the present invention includes: an amplifier circuit that receives a feedback voltage and a reference voltage, amplifies the difference between the feedback voltage and the reference voltage, and outputs the amplified difference voltage; an analog-to-digital converter that converts the amplified difference voltage into a digital code including two or more bits; and LDO regulators configured to output voltages based on the digital code. Each of the LDO regulators includes power transistors that output a corresponding one of the output voltages, drives one of the power transistors in a switching state, and drives each of the other transistors in a turned-on state or a turned-off state.
본 발명은 전자 장치에 관한 것이다. 본 발명의 전자 장치는 피드백 전압 및 기준 전압을 수신하고, 그리고 피드백 전압 및 기준 전압의 차이를 증폭하여 증폭된 차이 전압을 출력하는 증폭기 회로, 증폭된 차이 전압을 둘 이상의 비트들을 포함하는 디지털 코드로 변환하는 아날로그-디지털 변환기, 그리고 디지털 코드에 기반하여 출력 전압들을 출력하도록 구성되는 LDO(Low-Dropout) 레귤레이터들을 포함한다. LDO 레귤레이터들의 각각은 출력 전압들 중 대응하는 출력 전압을 출력하는 전력 트랜지스터들을 포함하고, 전력 트랜지스터들 중 하나를 스위칭 상태로 구동하고, 그리고 나머지 전력 트랜지스터들의 각각을 턴-온 상태 또는 턴-오프 상태로 구동한다. |
