... Note 2: Dropout voltage is defined as the input to output differential when the output voltage drops to 99% of its normal value. Note 3: Ground pin current is the regulator quiescent current. The total current drawn from the source is the sum of the load current to the ground current. Note +1V. For example, use V IN OUT(NOMINAL) temperature rise. © 2009 Exar Corporation ...
