†Notice: 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:

VR is the regulator output voltage setting.

2:

3:

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.

4:

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.

5:

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.

6:

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, JA). Exceeding the maximum allowable power dissipation causes the device to initi-

ate thermal shutdown. Please see Section 4.0 “Thermal Considerations” for more details.

7:

The minimum VIN has to justify the conditions: VIN  VR +VDROPOUT and VIN  2.7V for IL = 0.1 mA to IOUTMAX.
