NTE961

NTE961 Linear Integrated Circuit Voltage Regulator, Negative, 5V, 1A Description: The NTE961 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.

Regulation is measured at a constant junction temperature by pulse testing with a low duty cycle. Changes in output voltage due to heating effects must be taken into account. .420 (10.67) Max .110 (2.79) .500 (12.7) Max .147 (3.75) Dia Max .250 (6.35) Max .500 (12.7) Min .070 (1.78) Max GND .100 (2.54) VOUT VIN/Tab
