NTE Electronics 

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: (TA = +25°C unless otherwise specified)
