Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
Note 1:
Limits are 100% production tested at T
A
= +25
°
C. Limits over the operating temperature range are guaranteed through
correlation using statistical quality control (SQC) methods.
Note 2:
Dropout Voltage is defined as the LED_ to GND voltage at which current sink into LED_ drops 20% from the value at
V
LED
= 1V.
Note 3:
Dropout Voltage is defined as the LED_ to GND voltage at which current sink into LED_ drops 10% from the value at
V
LED
= 1V.
