The minimum V_IN has to meet two conditions: V_IN ≥ 2.7V and V_IN ≥ (V_R + 2.5%) + V_DROPOUT.
V_R is the regulator voltage setting. For example: V_R = 1.8V, 2.7V, 2.8V, 3.0V.

V_IN = 2.7V to 6.0V
4: Regulation is measured at a constant junction temperature using low duty-cycle pulse testing. Load regulation is tested
over a load range from 0.1 mA to the maximum specified output current. Changes in output voltage due to heating
effects are covered by the thermal regulation specification.
5: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal
value at a 1V differential.
6: Thermal regulation is defined as the change in output voltage at a time T after a change in power dissipation is applied,
excluding load or line regulation effects. Specifications are for a current pulse equal to I_LMAX at V_IN = 6V for t = 10 msec.
7: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction
temperature and the thermal resistance from junction-to-air (i.e., T_A, T_J, θ_JA). Exceeding the maximum allowable power
dissipation causes the device to initiate thermal shutdown. Please see Section 5.1 “Thermal Shutdown”, for more
details.
8: Output current is limited to 120 mA (typ) when V_OUT is less than 0.5V due to a load fault or short-circuit condition.
