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.

RADIATION TEST PROGRAM
The following chart is a summary of the test data collected on Radiation Tolerant
OMR7905/12/15 at various doses. The chart depicts the Total Radiation Dose that each device
was exposed 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.

OMNIREL’S RADIATION TEST PROCEDURE
•
•
•
•
•
Radiation Testing is performed on a single wafer by wafer basis.
Each wafer is identified and a random sample of 5 die per wafer is selected.
The die are then individually assembled in a hermetic package, data logged, electrically
tested, hi-rel screened and then submitted to radiation testing.
The packaged die are submitted to Steady State Total Dose radiation per Method 1019,
Condition A, at a dose rate of 50 RAD/sec biased at maximum supply voltage.
Final electrical test is performed within two hours of both Total Dose Radiation level from
a Cobalt 60 source and 168 hr, 100°C annealing process. Read and record data
including two non-radiated control samples.
The wafer is then qualified only if samples from wafers meet full electrical specifications
after 150% of total dose rating as specified in each product data sheet.
Omnirel’s controlling specifications are as follows: For Voltage Regulators the
controlling specification is MIL-PRF- 38534/MIL-STD-883. For Rectifiers/Schottky the
controlling specification is MIL-PRF-19500/MIL-STD-750.
