Application Hints (Continued)
Figures 6, 7 show the information for the SOT-223 package.
Figure 6 assumes a
θ
(J–A) of 74˚C/W for 1 ounce copper and
51˚C/W for 2 ounce copper and a maximum junction tem-
perature of 125˚C.
Please see AN-1028 for power enhancement techniques to
be used with the SOT-223 package.
Typical Applications
DS007781-41

FIGURE 7. Maximum Power Dissipation vs
T
AMB for the SOT-223 Package
Fixed Output Regulator
DS007781-13
Note: Bypass capacitors are recommended for optimum stability and
transient response, and should be located as close as possible to the
regulator.
