The NTE966 is a positive voltage regulator in a TO220 type package that employs current limiting, thermal shutdown, and safe-area compensation which makes it remarkably rugged under most operating conditions. With adequate heat sinking the NTE966 can deliver output currents in excess of 1 amp.
Regulation is measured at a constant junction temperature by pulse testing with a low duty cycle.
Changes in output voltage due to heating effects must be taken into account.
