NTE1908
Integrated Circuit
Positive 3 Terminal Voltage Regulator,
24V, 100mA
Description:
The NTE1908 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 NTE1908 remarkably rugged. No external components
are required in many applications.
The NTE1908 offers a substantial performance advantage over the traditional zener diode–resistor
combination, as output impedance and quiescent current are substantially reduced.
Features:
D Low Cost
D ±5% Tolerance
D Internal Short–Circuit Current Limiting
D Internal Thermal Overload Protection
D No External Components Required
D Complementary to NTE1909 Negative Regulator
