(1)
Minimum VIN is 1.800 V or VO + VDO, whichever is greater.
(2)
Test condition includes, output voltage VO = VO – 15% and pulse duration = 10 ms.
(3)
VImin = (VO + 1) or 1.8 V whichever is greater.
(4)
Dropout voltage is defined as the differential voltage between VO and VI when VO drops 100 mV below the value measured with
VI = VO + 1 V.
