The NTE1919 is a 3 terminal fixed negative voltage regulator in a TO3 type package designed for use in applications requiring a well regulated negative output voltage. Outstanding features include full power usage up to 1.5A of load current, internal current limiting, thermal shutdown, and safe area protection on the chip, providing protection of the series pass Darlington, under most operating conditions. Hermetically sealed steel packages are utilized for high reliability and low thermal resistance. A low?noise temperature stable band?gap reference is the key design factor insuring excellent temperature regulation of the NTE1919. This coupled to a very low output impedance insures superior load regulation.
