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 p ackage s uitable
for a multitude of a pplications t hat r equire a r egulated s upply o f u p t o 1 00mA. This d evice f eatures i nternal
current limiting a nd t hermal s hutdown m aking t he N TE1917 r emarkably r ugged. N o e xternal c omponents
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.
