Note 2: Specifications in bold type are limited to -40^oC<T_J<125^oC. Limits over temperature are guaranteed by design, but not
tested in production.
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.
Note 7: The error flag comparator includes 2.5% hysteresis.
Note 8: The FLAG pin will be enabled if EN pin voltage is high, and disabled if EN pin voltage is low.
