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.
