4. Performance guaranteed over the indicated operating temperature range by design and/or characterization 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. Measured when the output voltage falls 100 mV below the nominal output voltage (nominal output voltage is the voltage at the output meas-

ured under the condition VIN = VOUT + 0.5 V). In the case of devices having the nominal output voltage VOUT = 1.8 V the minimum input

to output voltage differential is given by the VIN(MIN) = 2.5 V.

6. Expected to disable the device when EN pin is floating.
