DESCRIPTION
These three terminal negative 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, they can deliver over 3.0 amps of output current. These units feature 2%
initial voltage tolerance, with 1.0% load regulation and .015% line regulation. 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. Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 30 W.
Power dissipation is determined by the input/output differential voltage and the output curren
t. Guaranteed maximum
power dissipation will not be available over the full input/output voltage range.
2. Guaranteed by design, characterization or correlation to other tested parameters.
3. The • denotes the specifications which apply over the full operating temperature range.
4. Refer to curves for typical characteristics versus total dose radiation levels.
RADIA TION TEST PROGRAM
The following chart is a summary of the test data collected on Radiation Tolerant OMR1033 at
various dose rates. The chart depicts the Total Radiation Dose that each device was exposed to
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.
