NTE NTE963

NTE963
Linear Integrated Circuit
Voltage Regulator, Negative, –6V, 1A
Description:
The NTE963 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.
Features:
D No External Components Required
D Internal Thermal Overload Protection
D Internal Short–Circuit Current Limiting
D Output Transistor Safe–Area Compensation
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
