ELECTRICAL CHARACTERISTICS (continued)
(V
+25°C, unless otherwise noted.) (Note 1)
Note 1: All devices are 100% production tested at T
Note 2: LED current specification includes both accuracy and matching tolerance.
Note 3: Dropout voltage is defined as the M2 or F3 to GND voltage at which current into M2 or F3 drops 10% from the value at 0.2V.
