Output Matching (note 1)
Note: 1. Output matching is calculated as the percent variation from I

/2.
2. With a fixed resistor on the brightness input some variation in brightness will occur from one device to another.
3. Absolute maximum for each output should be limited to 40mA.
4. The V

voltage should be regulated by the user. See Figure 7 and Figure 8 for allowable VO versus IO operation.
