Note 1: Dropout voltage is defined as the LED_ to GND voltage at which current sink into LED_ drops 20% from the value at LED_ = 1V.
Note 2: Dropout voltage is defined as the LED_ to GND voltage at which current sink into LED_ drops 10% from the value at LED_ = 1V.
Note 3: Specifications to -40°C are guaranteed by design and not production tested.
