NTE NTE965 Datasheet
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.

Note 1. Load and line regulation are specified at constant junction temperature. Changes in V
due to heating effects must be taken into account spearately. Pulse testing with low duty
cycle is used.
