Description

These three terminal positive regulators OMR117AHVNM are supplied in high density hermetically sealed packages and available Hi-Rel screened. All protective features are designed into the circuit, including thermal shutdown, current-limiting, and safe-area control. With heat sinking, these devices can deliver up to 1.5 amps of output current. These units OMR117AHVNM also feature output voltages that can be fixed from 1.2 volts to 57 volts using external resistors. These devices are ideally
suited for Space applications where small size, high reliability, and radiation tolerance is required. The high level of Radiation Tolerance of these devices makes OMR117AHVNM 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 select-ed, packaged and radiation tested to qualify each individual semiconductor wafer-by-wafer.
