All protective features are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 1.5 amps of output current. These units feature internally trimmed output voltages to ±1% or 2% of nominal voltage. Standard voltages are -5V, -12V, and -15V. However, other voltages are available up to -24 volts. 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.

RADIATION TEST PROGRAM The following chart is a summary of the test data collected on Radiation Tolerant OMR7905/12/15 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.

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. • • AVAILABLE PRODUCT SCREENING Standard Class Level Screening Per MIL-PRF-38535 Screen *Level B Test Method Wafer Lot Acceptance Non-destructive Bond Pull Pre-Cap Visual Inspection Temperature Cycle Constant Acceleration Visual Inspection PIND Test Serialization Pre-Burn-In Electrical Burn-In Interim Electrical PDA Calculations Final Electrical Fine & Gross Seal Radiographic Conformance Inspection** Final Visual Inspection --------2010 1010 2001 ------------Data Sheet 1015/160 hrs. ----5% Functional Data Sheet 1014 ----GR A 2009 *Level S Test Method 5007 ----2010 1010 2001 ----2020 ----Data Sheet 1015/240hrs.

Output bypass capacitors will improve the transient response of the regulator. The bypass capacitors, (2.2µF on the input, 1µF on the output) should be ceramic or solid tantalum which have good high frequency characteristics. If aluminum electrolytics are used, their values should be 10µF or larger. The bypass capacitors should be mounted with the shortest leads, and if possible, directly across the regulator terminals.
