Note 2:
Tested Limits are guaranteed and 100% tested in production.
Note 3:
Design Limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage ranges. These limits are used to
calculate outgoing quality levels.
Note 4:
Thermal Regulation is defined as the change in the output Voltage at a time T after a step change in power dissipation of 100 mW.
Note 5:
Temperature Coefficient of V
OUT
is defined as the worst case delta-V
OUT
measured at Specified Temperatures divided by the total span of the Specified
Temperature Range (See graphs). There is no guarantee that the Specified Temperatures are exactly at the minimum or maximum deviation.
Note 6:

C/W, junction to ambient, soldered into a PC board.
Note 7:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its Rated Operating Conditions (see Note 1 and Conditions).
Note 8:
Load regulation is measured on the output pin at a point
(/8
×
below the base of the package. Regulation is measured at constant junction temperature,
using pulse testing with a low duty cycle. Changes in output voltage due to heating effects are covered under the specification for thermal regulation.
