Note 1: Additional conditions for 8-pin versions are feedback tied to 5V Tap an Output tied to Output Sense

(Vout=5V) and Vshutdown<=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:Vref≤Vout≤(Vin-1V), 2.3V≤Vin≤30V, 100µA≤IL≤100mA, TJ≤TJMAX
