NTE1903 Integrated Circuit Negative Terminal Voltage Regulator, -12V, 100mA
Description: NTE1903 negative 3-terminal voltage regulator TO92 type package suitable numerous applications requiring 100mA. This device features thermal shutdown current limiting making NTE1903 remarkably rugged. most applications, external components required operation. NTE1903 useful on-card regulation other application where regulated negative voltage modest current level needed. This device offers substantial advantage over common resistor/zener diode approach.
