NTE1906
Integrated Circuit
Positive 3 Terminal Voltage Regulator,
18V, 100mA
Description:
The NTE1906 is a positive 3–terminal voltage regulator in a TO92 type package suitable for numerous
applications requiring up to 100mA. This device features thermal shutdown and current limiting making
the NTE1906 remarkably rugged. In most applications, no external components are required.
The NTE1906 is useful for on–card regulation or any other application where a regulated positive volt-
age at a modest current level is needed. This device offers a substantial advantage over he common
resistor/zener diode approach.
