DESCRIPTION
These three terminal positive adjustable voltage regulators are designed to provide 7.5A,
5A, 3A, and 1.5A with higher efficiency than conventional voltage regulators. The devices
are designed to operate to 1 Volt input to output differential and the dropout voltage is
specified as a function of load current. All devices are pin compatible with older three
terminal regulators. 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 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.
