DESCRIPTION

These three terminal positive regulators 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 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 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.
