VEN = Vcc = 5.5V
1) Difference between Vcc voltage and LED anode voltage at which ILED current drops 10% from nominal value
2) ILED Current Variations from specified value
3) ILED Current Variations per volt Vcc change for any given temperature
4) ILED Current Variations at VD change from 0.3V to 1.0V
5) EN input voltage should not exceed Vcc voltage at any condition
6) This condition is part of the LED current accuracy and it shall not exceed that specification
