NTE1961, NTE1963, NTE1965, NTE1967, NTE1971, NTE1973, NTE1975, NTE1977 Integrated Circuit Negative, 3–Terminal Voltage Regulator Description: The NTE1961 through NTE1977 series of monolithic 3–terminal negative voltage regulators employ internal current limiting, thermal shut–down, and safe–area compensation in an isolated TO220 type package making them essentially indestrucible. If adequate heat sinking is provided, they can deliver over 1A output current. These devices are intended for use as fixed voltage regulators in a wide range of applications including local (on card) regulation for elimination of distribution problems associated with single point regulation. In addition to use as fixed voltage regulators, they can be used with external components to obtain adjustable output voltages and currents.
