Note 2: All units are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 3: The dropout voltage is defined as V IN - V OUT , when V OUT is 100mV below the value of V OUT for V IN = V OUT + 0.5V.
Specification applies only when V OUT ≥ 2.5V.
Typical Operating Characteristics
V OUT1 = 3.3V, V OUT2 = 1.5V, load = 80mA (both output voltages), V IN = 3.8V, C OUT_ = 2.2μF, C BP = 0.01μF, C IN = 2.2μF, and T A = +25°C,
unless otherwise noted.
