ELECTRICAL CHARACTERISTICS
(VIN = +2.7V or VOUT(NOM) + 0.5V (whichever is greater), SHDN = IN, SS = open, SET = GND, COUT = 1µF, TA = -40°C to +85°C,
unless otherwise noted.) (Note 3)
Note 1: Dropout voltage is (VIN - VOUT) when VOUT falls to 100mV below the value of VOUT measured when VIN = VOUT(NOM) +0.5V.
Since the minimum input voltage is 2.7V, this specification is only meaningful when VOUT
≥ 2.7V.
Note 2: The output voltage is externally set using a resistive voltage-divider from OUT to SET.
Note 3: Specifications to -40°C are guaranteed by design, not production tested.
