NTE1913 Integrated Circuit Negative 3 Terminal Voltage Regulator, –5V, 1.5A Description: The NTE1913 is a 3 terminal fixed negative voltage regulator in a TO3 type package suitable for numerous applications requiring up to 1.5A. This device employs internal current limiting safe area protection and thermal shutdown for protection against virtually all overload conditions. Low ground pin current allows output voltage to be easily boosted above the preset value with a resister divider. The low quiescent current rain of the NTE1913 with a specified maximum change with line and load ensures good regulation in the voltages boosted mode.
