Figure 27. LP3964 TO-263 Package Typical Layout

10.3 Heatsinking TO-220 Packages

The thermal resistance of a TO-220 package can be reduced by attaching it to a heatsink or a copper plane on a

PC board.

The heatsink to be used in the application should have a heatsink-to-ambient thermal resistance,

RθHA ≤ RθJA − RθCH − RθJC

(7)

In this equation, RθCH is the thermal resistance from the junction to the surface of the heatsink and RθJC is the

thermal resistance from the junction to the surface of the case.
