NTE969 Datasheet, PDF (1/2 Pages) NTE Electronics – Linear Integrated Circuit Voltage Regulator, Negative, -15V, 1A

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.
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: (T_A = +25°C unless otherwise specified)
