NTE NTE1917

NTE1917
Integrated Circuit
Negative 3 Terminal Voltage Regulator,
–5V, 100mA
Description:
The NTE1917 voltage regulator is an inexpensive, easy–to–use 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 on–card 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 diode–resistor approach.
