The minimum V_IN has to meet two conditions: V_IN = 2.7V and V_IN = V_R + V_DROPOUT.
V_R is the regulator output voltage setting. For example: V_R = 1.8V, 2.7V, 2.8V, 2.85V, 3.0V, 3.3V.

6: Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested
over a load range from 1.0 mA to the maximum specified output current. Changes in output voltage due to heating
effects are covered by the thermal regulation specification.
7: 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.
8: 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_MAX at V_IN = 6V for T = 10 ms.
9: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction tem-
perature and the thermal resistance from junction-to-air (i.e. T_A, T_J, θ_JA).
10: Hysteresis voltage is referenced by V_R.
11: Time required for V_OUT to reach 95% of V_R (output voltage setting), after V_SHDN is switched from 0 to V_IN.
