DESCRIPTION
These three terminal positive 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, these
devices can deliver up to 1.5 amps of output current. These units also feature output voltages
that can be fixed from 1.2 volts to 57 volts using external resistors. 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.Load and Line Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.
Changes in output voltage due to heating effects must be taken into account separately.
2.If not tested, shall be guaranteed to the specified limits.
3.The • denotes the specifications which apply over the full 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
OMR117AHV at various doses. The char t depicts the Total Radiation Dose that
each device was e xposed 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.
