report, SPRA953.

When surface mount packages are used (SOT-223, TO-252), the junction to ambient thermal resistance can be reduced by increasing
the PCB copper area that is thermally connected to the package. See Heatsink Requirements for heatsink techniques.

IMAX = 1.5 A for the NDS (TO-3), NDE (TO-220), and KTT (TO-263) packages. IMAX = 1.0 A for the DCY (SOT-223) package.
IMAX = 0.5 A for the NDT (TO) and NDP (TO-252) packages. Device power dissipation (PD) is limited by ambient temperature (TA),
device maximum junction temperature (TJ), and package thermal resistance (θJA). The maximum allowable power dissipation at any
temperature is : PD(MAX) = ((TJ(MAX) – TA) / θJA). All Min. and Max. limits are ensured to TI's Average Outgoing Quality Level (AOQL).

Specifications and availability for military and space grades of LM117/883 can be found in the LM117QML data sheet (SNVS356).
Specifications and availability for military and space grades of LM117 can be found in the LM117JAN data sheet (SNVS365).
(3)
Regulation is measured at a constant junction temperature, using pulse testing with a low duty cycle. Changes in output voltage due to
heating effects are covered under the specifications for thermal regulation.
