Note 1: V_IN = V_IN3 = 3.3V. C_IN = 10µF, C_O1 = C_O2 = C_O3 = 3.3µF, C_B = 33nF. T_A = 25°C unless otherwise specified.
Note 2: Parameter is guaranteed by design, not production tested.
Note 3: The start-up time is defined as from SHDN pin goes high until Vo1 reaches regulation; or from SHDN3 goes high until VO3
reaches regulation.
Note 4: The dropout voltage is defined as Vind– Vod, where Vod is 50mV below V_OUT value measured at V_IN = 3.3V.
Note 5: Regulation is measured at constant junction temperature using low duty cycle pulse testing.
