NTE1909
Integrated Circuit
Negative 3 Terminal Voltage Regulator,
–24V, 100mA
Description:
The NTE1909 is a negative 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 NTE1909 remarkably rugged. In most applications, no external components are required for operation.
The NTE1909 is useful for on–card regulation or any other application where a regulated negative
voltage at a modest current level is needed. This device offers a substantial advantage over the com-
mon resistor/zener diode approach.
