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 and interface regions. In discrete devices the bulk of the damage is frequently manifested as a reduction in the gain and/or breakdown voltage of the device. The damage will usually anneal with time following the end of the radiation exposure. Due to this annealing, and to ensure a worst-case test condition MIL-STD-883 TM1019.7 calls out a dose rate of 50 to 300rad(Si)/s as Condition A and further specifies that the time from the end of an incremental radiation exposure and electrical testing shall be 1-hour or less and the total time from the end of one incremental irradiation to the beginning of the next incremental radiation step should be 2-hours or less. The work described in this report was performed to meet MIL-STD-883 TM1019.7 Condition A. 2.0. Radiation Test Apparatus The total ionizing dose testing described in this final report was performed using the facilities at Radiation Assured Devices’ Longmire Laboratories in Colorado Springs, CO. The high dose rate total ionizing dose (TID) source is a JLSA 84-21 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 radiation 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 <1rad(Si)/s to a maximum of approximately 120rad(Si)/s, determined by the distance from the source. For high-dose rate experiments the bias boards are placed in a radial fashion equidistant from the raised Co-60 rods with the distance adjusted to provide the required dose rate. The irradiator calibration is maintained by Radiation Assured Devices Longmire Laboratories using thermoluminescent dosimeters (TLDs)) traceable to the National Institute of Standards and Technology (NIST). Figure 2.1 shows a photograph of the JLSA 81-24 Co-60 irradiator at RAD’s Longmire Laboratory facility. RAD is currently certified by the Defense Supply Center Columbus (DSCC) for Laboratory Suitability under MIL STD 750.

Radiation Assured Devices 5017 N. 30th Street Colorado Springs, CO 80919 (719) 531-0800 Radiation Test Conditions The RH1573MJ8 low dropout PNP regulator driver described in this final report was tested using two bias conditions, statically biased with a 7V VIN and all pins tied to ground, see Appendix A for details on biasing conditions. These devices were irradiated to a maximum total ionizing dose level of 50krad(Si) with incremental readings at 10, 20, 30 and 50krad(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 ELDRS bias board was positioned in the Co-60 cell to provide the required 10mrad(Si)/s and was located inside a lead-aluminum box. The lead-aluminum box is required under MIL-STD-883G TM1019.7 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 testfixture 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 TLD dosimetry measurements just prior to the beginning of the total dose irradiations. The final dose rate for this work was 61.6rad(Si)/s with a precision of ±5%. An ISO 9001:2000 Certified Company 4 RLAT Report 08-126 090825 R1.1 4.0. Radiation Assured Devices 5017 N. 30th Street Colorado Springs, CO 80919 (719) 531-0800 Tested Parameters The following parameters were tested during the course of this work: 1. Input Quiescent Current (A) 2. Reference Voltage (V) 3. Line Regulation (V) 4. Load Regulation (V) 5. FB Pin Bias Current (A) 6. DRIVE Pin Current VFB=1.35V (A) 7. DRIVE Pin Current VFB=1.15V (A) 8.

LATCH Pin Charging Current (A) 14. LATCH Pin Latching Current (A) 15. VIN-VOUT Diff Threshold Latch Disable (V) 16. Minimum Bias Voltage (V) 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 values used is 2.742 per MIL HDBK 814 using one sided tolerance limits of 90/90 and a 5-piece sample size. This survival probability/level of confidence is consistent with a 22-piece sample size and zero failures analyzed using a lot tolerance percent defective (LTPD) approach. Note that the following criteria must be met for a device to pass the ELDRS testing: following the radiation exposure the unit shall pass the specification value and the average value for the each device must pass the specification value when the KTL limits are applied. If either of these conditions is not satisfied following the radiation exposure, then the lot could be logged as an RLAT failure. Further, MIL-STD-883G, TM 1019.7 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 An ISO 9001:2000 Certified Company 5 RLAT Report 08-126 090825 R1.1 Radiation Assured Devices 5017 N. 30th Street Colorado Springs, CO 80919 (719) 531-0800 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 “Enhanced Low Dose Rate Sensitivity (ELDRS) Radiation Testing of the RH1573MJ8 Low dropout PNP regulator driver for Linear Technology” to demonstrate that these parts do not exhibit ELDRS as defined in the current test method. 5.0. RLAT Test Results Using the conditions stated above, the RH1573MJ8 devices passed the radiation lot acceptance test to 50krad(Si) with no significant degradation to most of the measured parameters. Where radiation induced degradation was observed the degradation was not sufficient to cause the parameter to exceed the specification value. Note that VREF exceeded the upper datasheet specification after application of the 90/90 KTL statistics due to the relative large standard deviation of the sample population compared to the very tight specification limits. In our opinion this lot of material could be qualified to 50krad(Si) using larger samples sizes and an “attributes” approach, i.e. 22 units passing with 0 failures. Figures 5.1 through 5.16 show plots of all the measured parameters versus total ionizing dose. 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 postirradiation minimum and/or maximum specification value as defined in the datasheet and/or test plan.

Appendix D provides a list of all the figures in this results section to facilitate the location of a particular parameter. As seen clearly in these tables and figures, the pre- and post-irradiation data are well within the specification even after application of the KTL statistics (with certain exceptions, as noted below). The control units, as expected, show no significant changes to any of the parameters. Therefore we can conclude that the electrical testing remained under control during the course of the testing.

Summary / Conclusions The total ionizing dose testing described in this final report was performed using the facilities at Radiation Assured Devices’ Longmire Laboratories in Colorado Springs, CO. The high dose rate total ionizing dose (TID) source is a JLSA 84-21 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 radiation 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 <1rad(Si)/s to a maximum of approximately 120rad(Si)/s, determined by the distance from the source. In addition, all units-under-test received a 24hr room temperature and 168hr 100°C anneal, using the same bias conditions as the radiation exposure. The parametric data was obtained as “read and record” and all the raw data plus an attributes summary were presented in this report. The attributes data contains the average, standard deviation and the average with the KTL values applied. The KTL value used was 2.742 per MIL HDBK 814 using onesided tolerance limits of 99/90 and a 5-piece sample size. Note that the following criteria was used to determine the outcome of the testing: following the radiation exposure each parameter had to pass the specification value and the average value for the ten-piece sample must pass the specification value when the KTL limits are applied. If these conditions were not both satisfied following the radiation exposure, then the lot would be logged as an RLAT failure. Using the conditions stated above, the RH1573MJ8 devices passed the RLAT test to 50krad(Si) with no significant degradation to most of the measured parameters. Where radiation induced degradation was observed the degradation was not sufficient to cause the parameter to exceed the specification value. Note that VREF exceeded the upper datasheet specification after application of the 90/90 KTL statistics due to the relative large standard deviation of the sample population compared to the very tight specification limits. In our opinion this lot of material could be qualified to 50krad(Si) using larger samples sizes and an “attributes” approach, i.e. 22 units passing with 0 failures.

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 tests will be conducted using the LTS-2510 Digital Family Board, and the RH1573/LT1573 BGSS-080908 DUT board. 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 Tables C.2. The precision/resolution values were obtained either from test data or from the DAC resolution of the LTS2020. 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.
