description The present invention relates to an electronic device. According to the present invention, an operating method of a trimming circuit of a voltage regulator having improved accuracy which includes a comparator and a voltage distributor comprises the following steps of: determining a final voltage distributor code for the voltage distributor by comparing first voltage distributor output voltage with comparator reference voltage; and determining a final regulator code for the voltage regulator by comparing second voltage distributor output voltage with trimming reference voltage. The first voltage distributor output voltage is generated by dividing divided reference voltage according to the voltage distributor code input to the voltage distributor, and the second voltage distributor output voltage is generated by dividing output voltage of the voltage regulator according to the final voltage distributor code. 본 기술은 전자 장치에 관한 것으로, 본 기술에 따른 향상된 정확도를 갖는 전압 레귤레이터의 트리밍 회로의 동작 방법은 비교기와 전압분배기를 포함하는 전압 레귤레이터를 위한 트리밍 회로의 동작 방법이고, 제1 전압분배기 출력 전압과 비교기 기준 전압을 비교함으로써 전압분배기를 위한 최종 전압분배기 코드를 결정하는 단계 및 제2 전압분배기 출력 전압과 트리밍 기준 전압을 비교함으로써 전압 레귤레이터를 위한 최종 레귤레이터 코드를 결정하는 단계를 포함하고, 제1 전압분배기 출력 전압은 전압분배기에 입력되는 전압분배기 코드에 따라 분압 기준 전압을 분압함으로써 발생하고, 제2 전압분배기 출력은 최종 전압분배기 코드에 따라 전압 레귤레이터의 출력 전압을 분압함으로써 발생한다.
