NTE1979 Integrated Circuit Negative 3 Terminal Voltage Regulator, 8V, 100mA Description: The NTE1979 is a 3terminal fixed negative output voltage regulatgor in a TO92 type package designed for use in power circuits with current capacity up to 100mA. Stabilized fixed output voltage is obtained from unstable DC input voltage without the use of external components.
