*Stresses above those listed under "Absolute Maximum

Ratings" may cause permanent damage to the device. These

are stress ratings only and functional operation of the device

at these or any other conditions above those indicated in the

operation sections of the specifications is not implied.

Exposure to Absolute Maximum Rating conditions for

extended periods may affect device reliability.

Note 1:

The minimum VIN has to meet two conditions: VIN ≥ 2.7 and VIN =VR +VDROPOUT.

2:

VR is the regulator output voltage setting. For example: VR =2.8V, 3.0V.

3:

4:

Regulation is measured at a constant junction temperature using low duty cycle pulse testing. Load regulation is tested over a load range from

0.1mA 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 measured 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 5.0 Thermal Considerations section of this data sheet for more details.
