Abstract
Description
Claims (1)
- 공지의 정전압회로(1)의 출력측에 트랜지스터(Q2)의 에미터와 (Q1)의 콜렉터를 접속시키고, 트랜지스터(Q2)의 콜렉터는 저항(R2)에 접속하여 트랜지스터(Q1)의 베이스 및 다이오드(D1)에 접속시키며, 트랜지스터(Q2)의 베이스는 저항(R1)을 통하여 제너 다이오드(ZD1) 및 다이오드(D1)에 접속시키어 정전압회(1)로에서의 출력전압이 제너 다이오드(ZD1)의 제너전위(VZD1)보다 낮으면 트랜지스터(Q1,Q2)가 차단되게 구성 시킴을 특징으로 하는 정전압회로의 전압판별 회로.
