REMOTE SENSE VOLTAGE REGULATOR
EZ1087
DESCRIPTION
EZ1087 5.0A voltage regulator monolithic integrated circuit designed applications requiring well regulated positive output voltage with input-output differential voltage requirements where remote sensing output voltage desired compensate connector, wiring board trace resistances other voltage losses. Other outstanding features include full power usage 5.0A load current, internal current limiting, thermal shutdown. Specifications guarantee 3.30 output from 4.75 input.
FEATURES dropout performance, 1.3V max. Kelvin remote sense inputs Line regulation typically 0.015% Load regulation typically 0.1% 5-pin TO-220 package
