for the NDT (TO) and NDP (TO-252) packages. Device power dissipation (P
D
) is limited by ambient temperature (T
A
), device maximum
junction temperature (T
J
), and package thermal resistance (θ
JA
). The maximum allowable power dissipation at any temperature is :
P
D(MAX)
= ((T
J(MAX)
- T
A
)/θ
JA
). 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 datasheet (SNVS356).
Specifications and availability for military and space grades of LM117/JAN can be found in the LM117JAN datasheet (SNVS365).
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.
