= 1.5A for the NDS (TO-3), NDE (TO-220), and KTT (TO-263) packages. I

= 0.5A
for the NDT (TO), MDT (PFM), and NAJ (LCCC) 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).
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.
