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.
