NTE967 Linear Integrated Circuit Voltage Regulator, Negative, –12V, 1A Description: The NTE967 is a negative 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 they can deliver output currents in excess of 1.0 amperes.

Regulation is measured at a contant junction temperature by pulse teting with a low duty cycle. Changes in output voltage due to heating effects must be taken into account. .420 (10.67) Max .110 (2.79) .147 (3.75) Dia Max .500 (12.7) Max .250 (6.35) Max .500 (12.7) Min .070 (1.78) Max GND .100 (2.54) VOUT VIN/Tab
