NTE960
Integrated Circuit
3–Terminal Positive Voltage Regulator, 5V
The NTE960 fixed–voltage regulator is a monolithic integrated circuit in a TO220 type package designed for use in a wide variety of applications including local, on–card regulation. This regulator employs internal current limiting, thermal shutdown, and safe–area compensation. With adequate heatsinking it can deliver output currents in excess of 1.0 ampere.
Features:
D Output Current in Excess of 1.0 Ampere
D No External Components Reguired
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)

Note 1. Load and line regulation are specified at constant junction temperature. Changes in VO due
to heating effects must be taken into account separately. Pulse testing with low duty cycle
is used.
