Note 1:Additional conditions for 8-pin versions are FB pin tied to 5V_TAP, Output tied to Sense(V_OUT=5V) and
V_SHDN≤0.8V.
Note 2: 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.
Note 3: Comparator thresholds are expressed in terms of percentage value of voltage output.
Note 4: V_REF≤V_OUT≤(V_IN-1V), 2.3V≤V_IN≤30V, 100µA≤I_L≤100mA, T_J≤T_J(MAX)
