3. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.

4. Line regulation is defined as the change in output voltage for a change in input voltage. Load regulation is defined as the change in output

voltage for a change in output load current at a constant temperature. The limits for line and load regulation are contained within the refer-

5. The short circuit limit is for device protection. Maximum output current is guaranteed to be greater or equal to 3.0 A with a 6.0 A typical

as listed in the peak output limit specification.
