Note 1: Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing.
Note 2: Line and load regulation are guaranteed up to the maximum power dissipation (OMR183/60W, OMR184/45W, OMR185/30W,
OMR186/15W). Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum
power dissipation will not be available over the full input/output voltage range.
Note 3: I
FULL LOAD curve is defined as the minimum value of current limit as a function of input to output voltage.
Note that power
dissipation is only achievable over a limited range of input to output voltage.
Note 4: Dropout voltage is specified over the full output current range of the device.
Note 5: Refer to curves for typical characteristics versus total dose radiation levels.
