Notes:

1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.

Changes in output voltage due to heating effects must be taken into account separately.

2. Short Circuit protection is only assured up to VIN = 35V.

3. If not tested, shall be guaranteed to the specified limits.

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

5. Refer to curves for typical characteristics versus Total Dose Radiation Levels.

RADIATION TEST PROGRAM

The following chart is a summary of the test data collected on Radiation Tolerant

OMR7805/12/15 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.
