Note 1: The minimum VIN has to meet two conditions: VIN ≥ 2.7V and VIN ≥ (VR + 2.5%) + VDROPOUT
2: VR is the regulator voltage setting. For example: VR = 1.8V, 2.7V, 2.8V, 3.0V.

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 ILMAX at VIN = 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. TA, TJ, θJA). Exceeding the maximum allowable power
dissipation causes the device to initiate thermal shutdown. Please see Section 5.1, “Thermal Considerations”, for
more details.
