500mA, Low-Voltage Linear Regulator
in Tiny QFN
ELECTRICAL CHARACTERISTICS (continued)
(V IN = V OUT(SETPOINT) + 500mV or V IN = 2.25V whichever is greater, SET = GND, SHDN = IN, T A = -40 ° C to +85 ° C , unless otherwise
noted. Typical values are at T A = +25 ° C.) (Note 2)

Note 1: Dropout voltage is defined as V IN - V OUT , when V OUT is 100mV below the value of V OUT and when V IN = V OUT(NOM) + 0.5V.
For 2.25V ≤ V OUT ≤ 4V, dropout voltage limits are linearly interpolated from the values listed. For V OUT < 4V, dropout
voltage limit is equal to the value for V OUT = 4V.
Note 2: Specifications to -40 ° C are guaranteed by design, not production tested.
Typical Operating Characteristics
(V OUT = 3.3V, V IN = V OUT + 500mV, SHDN = IN, C IN = 1μF, C OUT = 10μF, T A = +25 ° C, unless otherwise noted.)
