Note 1:

The minimum V

IN has to meet two conditions: VIN ≥ 2.7V and VIN ≥ (VR + 2.5%) + VDROPOUT.

R is the regulator voltage setting. For example: VR = 1.8V, 2.7V, 2.8V, 3.0V.

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.

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.

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.

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, 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
