*1. Additional conditions for 8-pin versions are FB pin tied to 5VTAP, Output tied to Sense
(VOUT=5V) and VSHDN≤0.8V
*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.
*3. Comparator thresholds are expressed in terms of percentage value of voltage output.
*4. VREF≤VOUT≤(VIN-1V), 2.3V≤VIN≤30V, 100µA≤IL≤100mA, TJ≤TJ(M AX)
