300 kRAD RADIATION TOLERANT 1.5 AMP NEGATIVE FIXED VOLTAGE REGULATORS
300K Rad Tolerant Three Terminal, Negative Fixed Voltage Regulators In Hermetic Packages
Please see mechanical outlines herein
FEATURES
* * * * * * * Isolated & Non-Isolated Hermetic Packages Output Voltages: -5V, -12V, -15V (Other Voltages Available) Output Voltages Set Internally To 1% or 2% Built-In Thermal Overload Protection Short Circuit Current Limiting Radiation Tolerant up to 450 K Rad (Si) Available Hi-Rel Screened, Class B and Class S, MIL-STD-883
DESCRIPTION
These three terminal negative regulators are supplied in a high density hermetically sealed metal package and are 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 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.

OMNIREL'S RADIATION TEST PROCEDURE
* * * * * Radiation Testing is performed on a single wafer by wafer basis. 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, 100C 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.

TYPICAL APPLICATIONS
Input bypass capacitors are recommended for stable operation of the OM7900 series of regulators over the input voltage and output current ranges. Output bypass capacitors will improve the transient response of the regulator. The bypass capacitors, (2.2F on the input, 1F on the output) should be ceramic or solid tantalum which have good high frequency characteristics. If aluminum electrolytics are used, their values should be 10F or larger. The bypass capacitors should be mounted with the shortest leads, and if possible, directly across the regulator terminals.
