Description

These three terminal negative regulators OMR7812ST are supplied in a high density hermetically sealed metal package and are available hi-rel screened. All pro-tective features are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 1.5 amps of output current. These units OMR7812ST feature internally trimmed output voltages to ±1% or 2% of nominal voltage. Standard voltages are 5-V, +12V, and +15V. However, other voltages are available up to +24 volts. These devices OMR7812ST 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 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.
