Summary

 TC2014, TC2015 및 TC2185는 LP2980과 같은 구형 (바이폴라) 저전압 강하 레귤레이터를위한 고정밀(일반적으로 ±0.4%) CMOS 업그레이드입니다. 총 공급 전류는 일반적으로 55μA(바이폴라 레귤레이터보다 20~60 배 낮음)입니다. 이 디바이스의 주요 특징으로는 초 저잡음 동작(바이 패스 레퍼런스 포함), 매우 낮은 드롭 아웃 전압(일반적으로 45mV(TC2014)); 90mV(TC2015); 및 140mV(TC2185)의 부하에서 단계 변화에 신속하게 대응할 수 있습니다. 공급 전류는 0.5μA(최대)로 감소하고 셧다운 입력이 낮을 때 VOUT은 0으로 떨어집니다. 이 소자는 과전류 보호 기능도 통합하고 있습니다. TC2014, TC2015 및 TC2185는 1μF의 출력 커패시터로 안정적이며 최대 출력 전류는 각각 50mA, 100mA 및 150mA입니다. 더 높은 출력 버전에 대해서는 TC1107, TC1108 및 TC1173 (IOUT = 300mA) 데이터 시트를 참조하십시오.
