DESCRIPTION
These three terminal negative regulators are supplied in a high density hermetically sealed
metal package and are available hi-rel screened. All protective 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 feature internally trimmed output
voltages to ±1% or 2% of nominal voltage. Standard voltages are -5V, -12V, and
-15V. However, other voltages are available up to -24 volts. 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.
