REGULATOR MOUNTING
The tab of both packages is electrically connected to ground.
For best thermal performance, the tab of the DDPAK sur-
face-mount version should be soldered directly to a circuit-
board copper area. Increasing the copper area improves heat
dissipation. Figure 10 shows typical thermal resistance from
junction to ambient as a function of the copper area for the
DDPAK, Figure 11 shows the same relationship for the
SOT-223.
Although the tabs of the DDPAK and the SOT-223 are
electrically ground, they are not intended to carry any
current. The copper pad that acts as a heat sink should be
isolated from the rest of the circuit to prevent current flow
through the device from the tab to the ground pin. Solder pad
footprint recommendations for the various REG104 devices
are presented in Application Bulletin “Solder Pad Recom-
mendations for Surface-Mount Devices” (AB-132), avail-
able from the Texas Instruments web site (www.ti.com).
