NTE965 Linear Integrated Circuit Voltage Regulator, Negative, -8V, 1A
Description: The NTE965 voltage regulator 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.
