ELECTRICAL CHARACTERISTICS (continued)
(V IN1 = V IN2 = V IN3 = V DD = 3.6V, V AGND = V PGND1 = V PGND2 = 0V, circuit of Figure 2, T A = -40°C to +85°C, unless otherwise noted.
Typical values are at T A = +25°C.) (Note 1)

Limits are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design.
Dropout voltage is defined as the LED_ to GND voltage when the current into LED_ drops 10% from the value at V LED_ = 0.5V.
Ramp-up time is from 0mA to full scale; ramp-down time is from full scale to 0mA.
Output power is specified by a combination of a functional output current test and characterization analysis.
The dropout voltage is defined as V IN_ - V OUT when V OUT is 100mV below the nominal value of V OUT . The specification only
applies when V OUT ≥ 3.0V.
Typical Operating Characteristics
(V IN1 = V IN2 = V IN3 = V DD = 3.6V, V AGND = V PGND1 = V PGND2 = 0V, circuit of Figure 2, T A = +25°C, unless otherwise noted.)
