NOTE 1: Guaranteed by design.
NOTE 2: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value with V

+1V
applied to V
.
NOTE 3: Reference Voltage is measured between output and GND pins, with ADJ PIN tied to V
.
NOTE 4: in order to avoid any output voltage rise within the whole operating temperature range, due to output leakage current, a minimum
load current of 2mA is required.
