Additional conditions for 8-pin versions are feedback tied to 5V Tap an Output tied to Output Sense
(Vout=5V) and Vshutdown<=0.8V.
Dropout Voltage is defined as the input to output differential at which the output voltage drops 100mV below
its nominal value measured at 1V differential.
Comparator thresholds are expressed in terms of percentage value of voltage output.
