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.

Notes:
1.Load and Line Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Changes in output voltage due to heating effects must be taken into account separately.
2.If not tested, shall be guaranteed to the specified limits.
3.The • denotes the specifications which apply over the full temperature range.
4.Refer to curves for typical characteristics versus Total Dose Radiation Levels.
RADIATION TEST PROGRAM
The following chart is a summary of the test data collected on Radiation Tolerant
OMR117AHV 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.
