Texas Instruments

 

Description

The TPS735 low-dropout (LDO), low-power linear regulator offers excellent AC performance with very low ground current. High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient responses are provided while consuming a very low 45-μA (typical) ground current.
The TPS735 device is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a typical dropout voltage of 280 mV at 500 mA output. The TPS735 device uses a precision voltage reference and feedback loop to achieve overall accuracy of 2% (VOUT > 2.2 V) over all load, line, process, and temperature variations. This device is fully specified from TJ = –40°C to +125°C and is offered in a low-profile, 3 mm × 3 mm SON-8 package and a 2 mm × 2 mm WSON-6 package.

 

TPS735는 저전압 강하(LDO)와 저전력 특성을 갖춘 선형 레귤레이터로, 매우 낮은 접지 전류를 유지하면서 우수한 AC 성능을 제공합니다. 높은 전원 제거 비율(PSRR), 저소음, 빠른 시작 시간, 그리고 우수한 라인 및 부하 변동 응답 특성을 제공하며, 동작 시 소비 전류는 전형적으로 45 μA에 불과합니다.
이 제품은 세라믹 커패시터와 안정적으로 동작하며, 고급 BiCMOS 제조 공정을 활용해 출력 전류 500 mA에서 전형적인 드롭아웃 전압 280 mV를 달성합니다. TPS735는 정밀 전압 참조와 피드백 루프를 사용하여 부하, 라인, 공정, 온도 변동을 포함한 모든 조건에서 출력 전압(VOUT > 2.2 V)의 2% 정확도를 유지합니다. 이 장치는 TJ = –40°C에서 +125°C까지 완전 사양이 제공되며, 3 mm × 3 mm 크기의 낮은 높이의 SON-8 패키지와 2 mm × 2 mm WSON-6 패키지로 제공됩니다.
