Note 2: For the details of VIN range, please refer to (VIN-VOUT)*ILOAD≤maximum power dissipation (Figure 4).
Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value
which is measured at VOUT+1V applied to VIN.
Note 4: VIN=VOUT(NOMINAL)+1V.
Note 5: VEN ≤0.8V, VIN≤8V, VOUT=0V.
