) is limited by ambient temperature (T
A
), device maximum
junction temperature (T

), and package thermal resistance (θ
JA
). The maximum allowable power dissipation at any temperature is :

(2) Specifications and availability for military and space grades of LM117/883 can be found in the LM117QML datasheet (SNVS356).
Specifications and availability for military and space grades of LM117/JAN can be found in the LM117JAN datasheet (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.
