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.
