UCC283T-3G3

低压差3 -A线性稳压器系列 LOW-DROPOUT 3-A LINEAR REGULATOR FAMILY

description

The UCC283−3/−5/−ADJ family of positive linear series pass voltage regulators are tailored for low-drop-out applications where low quiescent power is important. Fabricated with a BiCMOS technology ideally suited for low input-to-output differential applications, the UCC283−5 passes 3 A while requiring only 0.45 V of typical input voltage headroom ensured 0.6-V dropout.
