Limits at T A = -40°C are guaranteed by design.
Output voltage is tested using a pulsed load current of less than 50ms duration.
Dropout voltage is defined as (V IN - V OUT ) when V OUT is 100mV below the value of V OUT for V IN = V OUT + 3V.
Startup time measured from 50% of V IN to 90% of V OUT .
Continuous short-circuit protection for V IN > 14V not guaranteed.
