NTE969
Linear Integrated Circuit
Voltage Regulator, Negative, –15V, 1A
Description:
The NTE969 voltage regulator employs current limiting, thermal shutdown, and safe–area com-
pensation which makes it remarkably rugged under most operating conditions. With adequate heat–
sinking they can deliver output currents in excess of 1.0 amperes.
