• Available Hi-Rel Screened, Class B and Class S, MIL-STD-883
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.

RADIA TION TEST PROGRAM
The following chart is a summary of the test data collected on Radiation Tolerant
OMR7805/12/15 at various doses. The chart depicts the Total Radiation Dose that
each device was e xposed to on a step stress irradiation basis prior to failure. Failure
is defined as any electrical test that does not meet the limits of the device per the
published data sheet specifications after radiation testing.
