1. Introduction
This report provides results of a low and high dose rate total dose test followed by an
accelerated annealing test (after high dose rate only) of the ISL75051SEH low dropout regulator
(‘LDO’). The test was conducted in order to determine the sensitivity of the part to total dose
irradiation and to the post high dose rate irradiation accelerated aging (‘anneal’) procedure required
by MIL-STD-883.
The ISL75051SxH is available in two versions differing in their total ionizing dose acceptance
testing flow. The ISL75051SRH is acceptance tested on a wafer by wafer basis to 100 krad(Si) at
high dose rate (50 – 300 rad(Si)/s) only. The ISL75051SEH is acceptance tested on a wafer by
wafer basis to 100 krad(Si) at high dose rate (50 – 300 rad(Si)/s) and to 50 krad(Si) at low dose rate
(0.01 rad(Si)/s). The ISL75051SRH and ISL75051SEH are otherwise identical parts and the results
reported in this document apply to both versions.
Method 1019 of MIL-STD-883 requires an accelerated aging test for all integrated circuits
containing MOS devices. The samples are to be irradiated to 1.5x the specified maximum total dose
at the Test Condition A dose rate of 50 – 300 rad(Si)/s. Following the final electrical testing
operation after the last irradiation downpoint, the parts are then annealed at 100oC under bias for
168 hours, followed by another electrical testing cycle. For the present test, the flow was as follows:
1. A high dose rate total dose test to 150krad(Si) was performed using the Intersil Palm
Bay Gammacell 60Co irradiator, which has a current dose rate of 50rad(Si)/s.
Downpoints were 0, 25, 50, 100 and 150krad(Si), with ATE data taken at each
downpoint. Samples were irradiated under bias and with all pins grounded, with a
sample size of 6 for each group. In addition 3 control units were used; these were
datalogged at each downpoint and were stored at room temperature in between
downpoints.
2. Both groups of samples were annealed at 100oC under bias for 168 hours. The bias
configuration was the standard SMD irradiation bias circuit, which is designed to
reverse bias as many transistor structures as practical while minimizing power
dissipation.
3. Following the anneal procedure, all samples and control units were electrically tested.
All parameters showed excellent stability at all downpoints.
In parallel to the high dose rate irradiation/anneal sequence, a low dose rate test was
performed with the objective of determining the low dose rate sensitivity of the part. For this test, the
flow was as follows:
1. The low dose rate total dose test to 150krad(Si) is in progress at this time and is
through the 100krad(Si) downpoint. The test was performed using the Intersil Palm
Bay low dose rate irradiator at a dose rate of 0.01rad(Si)/s. The 0, 50 and 100krad(Si)
downpoints are complete, with ATE data taken at each downpoint. Samples were
irradiated under bias and with all pins grounded, with a sample size of 4 for each
group. Control units were used but the data is not reported.
2. No anneal was performed after the low dose rate test.
As in the high dose rate test, all samples in the low dose rate test showed stable performance
to 50krad(Si), but at the 100krad(Si) downpoint a failure was encountered in the grounded
irradiation group. Failure analysis was performed with somewhat inconclusive results, with electrical
overstress during ATE testing found to be the most likely cause, so the failed part was removed
2
from the population. We note that low dose rate sensitivity testing has been performed on several
other parts using the P6 BiCMOS technology, and all of these parts were found to be ELDRS-free.
We will report the 100krad(Si) results for the remaining samples in this document, and a new test
has been started. No anneal was performed after the low dose rate test.

3: Part Description
The ISL75051SEH is a radiation hardened low voltage, high-current, single output low dropout
linear voltage regulator (LDO) specified for a 3.0A output current. The device operates over an input
voltage range of 2.2V to 5.5V and is capable of providing output voltages of 0.8V to 4V, with the
output voltage adjusted by an external resistor divider network. The ENABLE feature allows the part
to be placed into a low quiescent current shutdown mode. A submicron BiCMOS process is utilized
for this product family to deliver competitive analog performance, efficiency and overall value.
The ISL75051SEH overcurrent protection (OCP) pin allows the short circuit output current limit
threshold to be programmed with an external resistor. The BiCMOS design consumes significantly
lower quiescent current as a function of load in comparison to bipolar LDOs, which results in higher
efficiency and the ability to consider packages with smaller footprints. The quiescent current of the
part was traded off against a highly competitive load transient response, resulting in a superior total
AC regulation band for an LDO in this category.
The ISL75051SEH is implemented in the submicron P6 power management process, with
0.6um minimum ground rules and three layers of interconnect. Active devices include low voltage
CMOS and high voltage DMOS devices as well as complementary bipolar junction transistors. The
process is in volume production under MIL-PRF-38535 certification and is used for a wide range of
commercial power management devices. Figure 1 shows a pin assignment table for the part.

4: Test Description
4.1 Irradiation Facilities
The high dose rate total dose irradiation was performed using a Gammacell 220 60Co
irradiator located in the Palm Bay, Florida Intersil facility. The irradiation was done at a dose rate of
80 rad(Si)/s per a calculated dose rate table, in accordance with MIL-STD-883 Method 1019. The
168-hour anneal was performed at 100oC in a small oven, using the same bias board used for the
irradiations. The transfer time from the last ATE test to the start of the anneal was two minutes.
The low dose rate irradiation was performed using a Shepherd 484 irradiator at 0.01rad(Si)/s.
4.2 Test Fixturing
The configuration used for biased irradiation was in conformance with Standard Microcircuit
Drawing (SMD) 5962-11212.
4.3 Characterization equipment and procedures
All electrical testing at the irradiation downpoints and following the high temperature anneal
was performed at room temperature using the production Eagle ETS364 automated test equipment
(ATE) at the Intersil Palm Bay facility. The test program used was 53865A01_SPX5X rev D, which
is the released production test program. The same setup was used for all test points. Three
controls were run at each test point; no anomalous readings were observed at any time, see also
the variables data in Section 6, which plot the control unit data as well as the experimental samples.
All test results were datalogged. All parts passed the post-radiation room temperature SMD 596211212 limits at all downpoints.
4.4 Experimental matrix
The experimental matrix consisted of six samples irradiated at high dose rate with all pins
grounded, six samples irradiated at high dose rate under bias and three control units. Additionally,
four samples were irradiated at low dose rate with all pins grounded and four samples were
irradiated at low dose rate under bias.
Samples of the ISL75051SEH were drawn from production lot 53865A01-WPH2EEHCA,
wafer 01. Samples were packaged in the standard 18 lead ceramic flatpack, Intersil package code
KKB. All samples were processed through the standard burnin cycle before irradiation, as required
by MIL-STD-883, and were screened to the SMD 5962-11212 limits at room, low and high
temperatures before the start of total dose testing.
4.5 Downpoints
The downpoints for the high dose rate irradiations were 0krad(Si), 25krad(Si), 50krad(Si),
100krad(Si) and 150krad(Si), followed by a 168-hour anneal at +100oC. The downpoints to date for
the low dose rate irradiations are 0krad(Si), 50krad(Si) and 100krad(Si), with a 150krad(Si)
downpoint expected for the fourth quarter of 2012. No anneal was performed after the low dose rate
test.

5: Results
5.1 Test results
The high dose rate test and subsequent anneal the ISL75051SEH is complete and showed no
reject devices after irradiation to 150krad(Si) and anneal for 168 hours at 100oC, screening to the
SMD 5962-11212 post-irradiation limits.
All samples in the low dose rate test showed stable performance to 50krad(Si), but at the
100krad(Si) downpoint a failure was encountered in the grounded irradiation group. Failure analysis
was performed and while not conclusive showed electrical overstress during ATE testing as the
most likely cause. The failed part was removed from the population. We note that low dose rate
sensitivity testing has been performed on several other parts using the P6 BiCMOS technology, and
all of these parts were found to be ELDRS-free. We will report the 100krad(Si) results for the
remaining samples in this document, and a new test has been started to further validate the low
dose rate performance of the part. No anneal was performed after the low dose rate test.
5.2 Discussion and Conclusions
All parameters displayed excellent stability and were well within the post-irradiation SMD limits
both after the irradiations and the high temperature accelerated aging step. Some parameters
showed change over the tests, and we discuss these below.
Figs. 5, 6, 8 and 9: These figures plot the enable rising and falling thresholds for the 2.2V and
6.0V input cases. The parameters show a decrease over high dose rate and then recover to the
pre-radiation value after anneal, with no bias sensitivity. The low dose rate data was stable. We
note that this result is related to the failed sample encountered at the 100krad(Si) level; failure
analysis showed a leaky NMOS device in the Enable input circuitry, but the threshold levels for the
pin remained stable. The failure is unexpected and therefore further suspect, as MOS devices are
not considered low dose rate sensitive. Additionally the high dose rate data showed excellent
stability.
Figs. 12 and 27: These figures show the DC output voltage for the 0.52V output, 2.2V input,
no load, and 5.0V output, 6.0V input, 3A load cases, respectively. Both parameters show an
increase for biased irradiation and a decrease for grounded irradiation, but in both cases the
changes are minor. No other DC output voltage parameters show this behavior. The low dose rate
data was stable.
Fig. 30 and 31: These figures plot the line and load regulation for 1.8V out. The data shows a
gradual decrease toward zero over irradiation, then a recovery to near the pre-radiation value. This
is the most ‘rebound-like’ response observed in the data, but the parameter remained well within
the specifications. The corresponding line and load regulation data at 1.5V out and 5.0V out did not
show this behavior. The control units and the low dose rate data were stable.
Figure 43, 44, 46 and 47: These curves show the PGOOD falling and rising threshold for the
6.0V and 2.2V in cases. The parameters were stable over irradiation and then showed an increase
to above the pre-radiation value, but all remained well within the specifications. The control units
and the low dose rate data were stable.
5
Figure 53 and 54: These figures show the output short circuit current at 2.2V in, for the
RSET=5.11K and 511Ω cases. The parameters showed a gradual increase over irradiation,
followed by a decrease after the anneal, but all remained well within the specifications. The control
units and the low dose rate data were stable.
We conclude that all parameters remained well within the specifications over a 100oC anneal
under bias for 168 hours, indicating a minimal ‘rebound’ response of the P6 process used for the
part. We also conclude that the part displays excellent low dose rate hardness to 50krad(Si) and
that the ISL75051SEH shows little or no dose rate or bias sensitivity. The low dose rate test will
continue to 150krad(Si) with the failed device removed from the population, while a second low
dose rate test at 0.01rad(Si)/s is currently being planned.
6: Variables data
The plots in Figures 2 through 56 show data for key ISL75051SEH parameters at all
downpoints. The plots show the median as a function of total dose for each of the irradiation
conditions; we chose to use the median because of the relatively small sample size of each group.
All parts showed excellent stability over high and low dose rate irradiation and over the subsequent
anneal and remained well within the specification limits at all downpoints. The data repeatability
was excellent, as evidenced by stable control unit readings at all downpoints.
