NEGATIVE ADJUSTABLE VOLTAGE REGULATORS

FEATURES

• Available in Three Hermetic Package Styles

• Radiation Tolerant up to 30 k Rad (Si)

• Reference Voltage Set Internally to ±2%

• Built-In Thermal Ov erload Protection

• Short Circuit Current Limiting

• Product Is Available Screened To Class B and Class S, MIL-STD-883

DESCRIPTION

These three terminal negative regulators are supplied in high density hermetically
sealed packages and 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 3.0 amps of output current. These units feature 2%
initial voltage tolerance, with 1.0% load regulation and .015% line regulation. 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.

Notes:

1. Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 30 W.

Power dissipation is determined by the input/output differential voltage and the output curren

t. Guaranteed maximum

power dissipation will not be available over the full input/output voltage range.

2. Guaranteed by design, characterization or correlation to other tested parameters.

3. The • denotes the specifications which apply over the full operating temperature range.

4. Refer to curves for typical characteristics versus total dose radiation levels.

RADIA TION TEST PROGRAM

The following chart is a summary of the test data collected on Radiation Tolerant OMR1033 at
various dose rates. The chart depicts the Total Radiation Dose that each device was exposed to
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.

Test Points X X

OMR1033SR

• 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 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.
