4. Performance guaranteed over specified operating conditions by design, guard banded test limits, and/or characterization, production tested at
TJ = TA = 25°C. Low duty cycle pulse techniques are used during testing to maintain the junction temperature as close to ambient as possible.
5. Typical values are based on design and/or characterization.
6. Other fixed output voltages available at 0.9 V, 1.2 V, 1.5 V, 1.8 V, 3.0 V, 3.3 V per request.
