1.0. Overview and Background
It is well known that total dose ionizing radiation can cause parametric degradation and ultimately
functional failure in electronic devices. The damage occurs via electron-hole pair production, transport
and trapping in the dielectric regions. In advanced CMOS technology nodes (0.6µm and smaller) the
bulk of the damage is manifested in the thicker isolation regions, such as shallow trench or local
oxidation of silicon (LOCOS) oxides (also known as "birds-beak" oxides). However, many linear and
mixed signal devices that utilize bipolar minority carrier elements exhibit an enhanced low dose rate
sensitivity (ELDRS). At this time there is no known or accepted a priori method for predicting
susceptibility to ELDRS or simulating the low dose rate sensitivity with a "conventional" room
temperature 50-300rad(Si)/s irradiation (Condition A in MIL-STD-883 TM 1019.8). Over the past 10
years a number of accelerating techniques have been examined, including an elevated temperature
anneal, such as that used for MOS devices (see ASTM-F-1892 for more technical details) and irradiating
at various temperatures. However, none of these techniques have proven useful across the wide variety
of linear and/or mixed signal devices used in spaceborne applications.
The latest requirement incorporated in MIL-STD-883 TM 1019 requires that devices that could
potentially exhibit ELDRS "shall be tested either at the intended application dose rate, at a prescribed
low dose rate to an overtest radiation level, or with an accelerated test such as an elevated temperature
irradiation test that includes a parameter delta design margin". While the recently released MIL-STD883 TM 1019 allows for accelerated testing, the requirements for this are to essentially perform a low
dose rate ELDRS test to verify the suitability of the acceleration method on the component of interest
before the acceleration technique can be instituted. Based on the limitations of accelerated testing and to
meet the requirements of MIL-STD-883 TM1019.8 Condition D, we have performed a low dose rate test
at 10mrad(Si)/s.
2.0. Radiation Test Apparatus
The low dose rate testing described in this final report was performed using the facilities at Aeroflex
RAD's Longmire Laboratories in Colorado Springs, CO. The low dose rate source is a GB-150 irradiator
modified to provide a panoramic exposure. The Co-60 rods are held in the base of the irradiator heavily
shielded by lead. During the irradiation exposures the rod is raised by an electronic timer/controller and
the exposure is performed in air. The dose rate for this irradiator in this configuration ranges from
approximately 1mrad(Si)/s to a maximum of approximately 50rad(Si)/s, determined by the distance
from the source. For low dose rate testing described in this report, the devices are placed approximately
2-meters from the Co-60 rods. The irradiator calibration is maintained by Aeroflex RAD's Longmire
Laboratories using air ionization chamber (AIC) dosimetry traceable to the National Institute of
Standards and Technology (NIST). Figure 2.1 shows a photograph of the GB-150 Co-60 irradiator at
Aeroflex RAD's Longmire Laboratory facility.

3.0. Radiation Test Conditions
The RH3080MK Adjustable Low Dropout Regulator described in this final report were irradiated using
a single-sided supply potential of 3V and with all pins tied to ground, that is biased and unbiased. See
Appendix B for details on the biasing conditions during radiation exposure. In our opinion, this bias
circuit satisfies the requirements of MIL-STD-883H TM1019.8 Section 3.9.3 Bias and Loading
Conditions which states "The bias applied to the test devices shall be selected to produce the greatest
radiation induced damage or the worst-case damage for the intended application, if known. While
maximum voltage is often worst case some bipolar linear device parameters (e.g. input bias current or
maximum output load current) exhibit more degradation with 0 V bias."
The devices were irradiated to a maximum total ionizing dose level of 50krad(Si) with incremental
readings at 5krad(Si), 10krad(Si), 20krad(Si) and 30krad(Si). Electrical testing occurred within one hour
following the end of each irradiation segment. For intermediate irradiations, the units were tested and
returned to total dose exposure within two hours from the end of the previous radiation increment. The
radiation exposure bias board was positioned in the Co-60 cell to provide the targeted dose rate and was
located inside a lead-aluminum enclosure. The lead-aluminum enclosure is required under MIL-STD883H TM1019.8 Section 3.4 that reads as follows: "Lead/Aluminum (Pb/Al) container. Test specimens
shall be enclosed in a Pb/Al container to minimize dose enhancement effects caused by low-energy,
scattered radiation. A minimum of 1.5 mm Pb, surrounding an inner shield of at least 0.7 mm Al, is
required. This Pb/Al container produces an approximate charged particle equilibrium for Si and for
TLDs such as CaF2. The radiation field intensity shall be measured inside the Pb/Al container (1)
initially, (2) when the source is changed, or (3) when the orientation or configuration of the source,
container, or test-fixture is changed. This measurement shall be performed by placing a dosimeter (e.g.,
a TLD) in the device-irradiation container at the approximate test-device position. If it can be
demonstrated that low energy scattered radiation is small enough that it will not cause dosimetry errors
due to dose enhancement, the Pb/Al container may be omitted".
The final dose rate within the lead-aluminum box was determined based on air ionization chamber
(AIC) dosimetry measurements just prior to the beginning of the total dose irradiations. The final dose
rate for this work was 10mrad(Si)/s with a precision of ±5%.

4.0. Tested Parameters
During the enhanced low dose rate sensitivity testing the following electrical parameters were measured
pre- and post-irradiation:
1. SET Pin Current (A) @ Vin=1V Vc=2V IL=1mA
2. Output Offset Voltage (V) @ Vin=1V Vc=2V IL=1mA
3. ISET Line Regulation (nA/V) @ Vc=2 to 26V IL=1mA
4. VOS Line Regulation (mV/V) @ Vc=2 to 26V IL=1mA
5. ISET Load Regulation (A) @ IL=1mA to 100mA
6. VOS Load Regulation (V) @ IL=1mA to 100mA
7. VCONTROL Pin Current (A) @ Vin=1V Vc=2V IL=100mA
8. Minimum Load Current (A) @ Vin=Vc=10V Vo=0.1V
9. Minimum Load Current (A) @ Vin=Vc=26V Vo=0.1V
10. VCONTROL Dropout Voltage (V) @ Vin=1V IL=100mA
11. VIN Dropout Voltage (V) @ Vc=2V IL=100mA
Appendix C details the measured parameters, test conditions, pre-irradiation specification and
measurement resolution for each of the measurements.
The parametric data was obtained as "read and record" and all the raw data plus an attributes summary
are contained in this report as well as in a separate Excel file. The attributes data contains the average,
standard deviation and the average with the KTL values applied. The KTL value used in this work is
2.742 per MIL-HDBK-814 using one sided tolerance limits of 90/90 and a 5-piece sample size. The
90/90 KTL values were selected to match the statistical levels specified in the MIL-PRF-38535
sampling plan for the qualification of a radiation hardness assured (RHA) component. Note that the
following criteria must be met for a device to pass the low dose rate test: following the radiation
exposure each of the 5 pieces irradiated under electrical bias shall pass the specification value. The units
irradiated without electrical bias and the KTL statistics are included in this report for reference only. If
any of the 5 pieces irradiated under electrical bias exceed the device post radiation data sheet
specification limits, then the lot could be logged as a failure.
Further, MIL-STD-883H, TM 1019.8 Section 3.13.1.1 Characterization test to determine if a part
exhibits ELDRS' states the following: Select a minimum random sample of 21 devices from a
population representative of recent production runs. Smaller sample sizes may be used if agreed upon
between the parties to the test. All of the selected devices shall have undergone appropriate elevated
temperature reliability screens, e.g. burn-in and high temperature storage life. Divide the samples into
four groups of 5 each and use the remaining part for a control. Perform pre-irradiation electrical
characterization on all parts assuring that they meet the Group A electrical tests. Irradiate 5 samples
under a 0 volt bias and another 5 under the irradiation bias given in the acquisition specification at 50300 rad(Si)/s and room temperature. Irradiate 5 samples under a 0 volt bias and another 5 under
irradiation bias given in the acquisition specification at < 10mrad(Si)/s and room temperature. Irradiate

all samples to the same dose levels, including 0.5 and 1.0 times the anticipated specification dose, and
repeat the electrical characterization on each part at each dose level. Post irradiation electrical
measurements shall be performed per paragraph 3.10 where the low dose rate test is considered
Condition D. Calculate the radiation induced change in each electrical parameter (Δpara) for each
sample at each radiation level. Calculate the ratio of the median Δpara at low dose rate to the median
Δpara at high dose rate for each irradiation bias group at each total dose level. If this ratio exceeds 1.5
for any of the most sensitive parameters then the part is considered to be ELDRS susceptible. This test
does not apply to parameters which exhibit changes that are within experimental error or whose values
are below the pre-irradiation electrical specification limits at low dose rate at the specification dose.
Therefore, the data in this report can be analyzed along with the high dose rate report titled "Total
Ionizing Dose (TID) Radiation Testing of the RH3080MK Adjustable Low Dropout Regulator for
Linear Technology" to demonstrate that these parts do not exhibit ELDRS as defined in the current test
method.

5.0. ELDRS Test Results
Based on this criterion the RH3080MK Adjustable Low Dropout Regulator (from the lot traceability
information provided on the first page of this test report) PASSED the enhanced low dose rate
sensitivity test to the maximum tested dose level of 50krad(Si) with one exception, ISET Line
Regulation was out of specification. Note that the variation in ISET Line Regulation of the irradiated
units is due to the instruments measurement resolution/precision (see Table C2).
Figures 5.1 through 5.12 show plots of all the measured parameters versus total ionizing dose while
Tables 5.1 - 5.12 show the corresponding raw data for each of these parameters. In the data plots the
solid diamonds are the average of the measured data points for the sample irradiated under electrical bias
while the shaded diamonds are the average of the measured data points for the units irradiated with all
pins tied to ground. The black lines (solid or dashed) are the average of the data points after application
of the KTL statistics on the sample irradiated in the biased condition while the shaded lines (solid or
dashed) are the average of the data points after application of the KTL statistics on the sample irradiated
in the unbiased condition. The red dotted line(s) are the pre- and/or post-irradiation minimum and/or
maximum specification value as defined in the datasheet and/or test plan.
In addition to the radiation test results, the data plots and tables described above contain anneal data.
The anneals are performed to better understand the underlying physical mechanisms responsible for
radiation-induced parametric shifts and are not part of the criteria used to establish whether or not the lot
passes or fails the low dose rate test. In all cases the parts either improved or exhibited no change during
the anneal.
The control units, as expected, show no significant changes to any of the parameters. Therefore we can
conclude that the electrical testing remained in control throughout the duration of the tests and the
observed degradation was due to the radiation exposure. Appendix D lists the figures used in this section
to facilitate the location of a particular parameter.

Figure 5.3. Plot of ISET Line Regulation (nA/V) @ Vc=2 to 26V IL=1mA versus total dose. The solid diamonds
are the average of the measured data points for the samples irradiated under electrical bias while the shaded
diamonds are the average of the measured data points for the samples irradiated with all pins tied to ground. The
black lines (solid and/or dashed) are the upper and/or lower confidence limits, as determined by KTL statistics, on
the samples irradiated under electrical bias while the gray lines (solid and/or dashed) are the upper and/or lower
confidence limits, as determined by KTL statistics, on the samples irradiated in the unbiased condition. The red
dotted line(s) are the pre- and/or post-irradiation minimum and/or maximum specification value as defined in the
datasheet and/or test plan.

Figure 5.6. Plot of VOS Load Regulation (V) @ IL=1mA to 100mA versus total dose. The solid diamonds are
the average of the measured data points for the samples irradiated under electrical bias while the shaded diamonds
are the average of the measured data points for the samples irradiated with all pins tied to ground. The black lines
(solid and/or dashed) are the upper and/or lower confidence limits, as determined by KTL statistics, on the
samples irradiated under electrical bias while the gray lines (solid and/or dashed) are the upper and/or lower
confidence limits, as determined by KTL statistics, on the samples irradiated in the unbiased condition. The red
dotted line(s) are the pre- and/or post-irradiation minimum and/or maximum specification value as defined in the
datasheet and/or test plan.

6.0. Summary / Conclusions
The low dose rate testing described in this final report was performed using the facilities at Aeroflex
RAD's Longmire Laboratories in Colorado Springs, CO. The low dose rate source is a GB-150 irradiator
modified to provide a panoramic exposure. The Co-60 rods are held in the base of the irradiator heavily
shielded by lead. During the irradiation exposures the rod is raised by an electronic timer/controller and
the exposure is performed in air. The dose rate for this irradiator in this configuration ranges from
approximately 1mrad(Si)/s to a maximum of approximately 50rad(Si)/s, determined by the distance
from the source.
The parametric data was obtained as "read and record" and all the raw data plus an attributes summary
are contained in this report as well as in a separate Excel file. The attributes data contains the average,
standard deviation and the average with the KTL values applied. The KTL value used in this work is
2.742 per MIL-HDBK-814 using one sided tolerance limits of 90/90 and a 5-piece sample size. The
90/90 KTL values were selected to match the statistical levels specified in the MIL-PRF-38535
sampling plan for the qualification of a radiation hardness assured (RHA) component. Note that the
following criteria must be met for a device to pass the low dose rate test: following the radiation
exposure each of the 5 pieces irradiated under electrical bias shall pass the specification value. The units
irradiated without electrical bias and the KTL statistics are included in this report for reference only. If
any of the 5 pieces irradiated under electrical bias exceed the device post radiation data sheet
specification limits, then the lot could be logged as a failure.
Based on this criterion the RH3080MK Adjustable Low Dropout Regulator (from the lot traceability
information provided on the first page of this test report) PASSED the enhanced low dose rate
sensitivity test to the maximum tested dose level of 50krad(Si) with one exception, ISET Line
Regulation was out of specification. Note that the variation in ISET Line Regulation of the irradiated
units is due to the instruments measurement resolution/precision (see Table C2). Further, the data in this
report can be analyzed along with the high dose rate report titled "Total Ionizing Dose (TID) Radiation
Testing of the RH3080MK Adjustable Low Dropout Regulator for Linear Technology" to demonstrate
that these parts do not exhibit ELDRS as defined in MIL-STD-883H, TM 1019.8.

Appendix C: Electrical Test Parameters and Conditions
The expected ranges of values as well as the measurement conditions are taken from Linear Technology
RH3080MK SPEC NO. 05-08-5246 REV. 0. All electrical tests for this device are performed on one of
Aeroflex RAD’s LTS2020 Test Systems. The LTS2020 Test System is a programmable parametric
tester that provides parameter measurements for a variety of digital, analog and mixed signal products
including voltage regulators, voltage comparators, D to A and A to D converters. The LTS2020 Test
System achieves accuracy and sensitivity through the use of software self-calibration and an internal
relay matrix with separate family boards and custom personality adapter boards. The tester uses this
relay matrix to connect the required test circuits, select the appropriate voltage / current sources and
establish the needed measurement loops for all the tests performed. The measured parameters and test
conditions are shown in Table C.1.
A listing of the measurement precision/resolution for each parameter is shown in Table C.2. The
precision/resolution values were obtained from test data or from the DAC resolution of the LTS-2020
for the particular test shown, whichever is greater. To generate the precision/resolution shown in Table
C.2, one of the units-under-test was tested repetitively (a total of 10-times with re-insertion between
tests) to obtain the average test value and standard deviation. Using this test data MIL-HDBK-814 90/90
KTL statistics were applied to the measured standard deviation to generate the final measurement range.
This value encompasses the precision/resolution of all aspects of the test system, including the LTS2020
mainframe, family board, socket assembly and DUT board as well as insertion error. In some cases, the
measurement resolution is limited by the internal DACs, which results in a measured standard deviation
of zero. In these instances the precision/resolution will be reported back as the LSB of the DAC.
Note that the testing and statistics used in this document are based on an “analysis of variables”
technique, which relies on small sample sizes to qualify much larger lot sizes (see MIL-HDBK-814, p.
91 for a discussion of statistical treatments). Not all measured parameters are well suited to this
approach due to inherent large variations. If necessary, larger samples sizes could be used to qualify
these parameters using an “attributes” approach.
