NTE964 NTE964 Integrated Circuit 3­Terminal Positive Voltage Regulator, 8V The NTE964 NTE964 fixed­voltage regulator is a monolithic integrated circuit in a TO220 type package designed for use in a wide variety of applications including local, on­card regulation. This regulator employs internal current limiting, thermal shutdown, and safe­area compensation. With adequate heatsinking it can deliver output currents in excess of 1.0 ampere. Although designed primarily as a fixed voltage regulator, this device can be used with external components to obtain adjustable voltages and currents.
