wise specified.
Note 3: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
Note 4: Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load
regulation in the load range from 0.1mA to 150mA. Changes in output voltage due to heating effects are covered by the thermal
regulation specification.
Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal
value measured at 1V differential.
Note 6: Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the
supply is the sum of the load current plus the ground pin current.
