NTE1917 Integrated Circuit Negative 3 Terminal Voltage Regulator, 5V, 100mA Description: The NTE1917 voltage regulator is an inexpensive, easytouse device in a TO92 type package suitable for a multitude of applications that require a regulated supply of up to 100mA. This device features internal current limiting and thermal shutdown making the NTE1917 remarkably rugged. No external components are required in many applications. The NTE1917 is useful for oncard regulation or any other application where a regulated negative voltage at a modest current level is needed. It offers a substantial performance advantage over the common zener dioderesistor approach.
