Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature
range.
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.
