stored in conductive material. Protect devices from static dis-

charge and static fields. Stresses above those listed under

Absolute Maximum Ratings may cause permanent damage to

the device. These are stress ratings only and functional oper-

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 V

7:

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable juction temperature and the

thermal resistance from junction-to-air (i.e. T

thermal shutdown. Please see Section 5.0 “Thermal Considerations” of this data sheet for more details.
