Typical Applications (Continued)
Operating with a High Voltage Supply (Dot Mode Only)
DS005104-29
The LED currents are approximately 10 mA, and the LM3915 outputs operate in saturation for minimum dissipation.
*
This point is partially regulated and decreases in voltage with temperature. Voltage requirements of the LM3915 also decrease with temperature.
