Note 1:
Limits are 100% production tested at TA = +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 VLED = 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 VLED = 1V.
