The uPC78L05J is housed in a self-standing package, but this is a TO-92 package, which doesn't have a heat sink attached. We therefore ask you to design your product based on the value of the thermal resistance between the junction and ambient air. Note that self-standing packages with a heat sink attached do have a specification for the junction-case thermal resistance.
Also note that because through-pin (insertion type) products are phased-out products, you can use the surface-mount product uPC78L05T in place of the uPC78L05J.
