NTE969
Linear Integrated Circuit
Voltage Regulator, Negative, –15V, 1A
Description:
The NTE969 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
