2. Performance guaranteed over the indicated operating temperature range by design 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.

3. Contact factory for other voltage options.

4. Measured when output voltage falls 100 mV below the regulated voltage at Vin = Vout + 0.5 V if Vout < 2.5 V, then VDO = Vin - Vout at Vin = 2.5 V.

5. Guaranteed by design and characterization.

6. Expected to disable device when CE pin is floating.
