Description

These three terminal negative regulators OMR1033ST are supplied in high density hermetically sealed packages and available Hi-Rel Screened. All protective fe-atures are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 3.0 amps of output current. These units OMR1033ST feature 2% initial voltage tolerance, with 1.0% load regulation and .015% line regulation. These devices are id-eally suited for Space applications where small size, high reliability, and radiation tolerance is required. The high level of Radiation olerance of these devices OMR1033ST makes them a desirable choice for LEO and many MEO and GEO communication satellites. Radiation testing is performed on a single wafer by wafer basis. Random die samples per wafer are selected, packaged and radiation tested to qualify each individual semiconductor wafer-by-wafer.
