| NTE1979 Integrated Circuit Negative 3 Terminal Voltage Regulator, -8V, 100mA Description: The NTE1979 is a 3-terminal 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. Features: D No External Components D Output Current in Excess of 100mA D Built-In Short-Circuit Current Limiting D Built-In Thermal Overload Protection Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Input Voltage, VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -35V Power Dissipation (Note 1), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 650mW Operating Ambient Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +80C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +150C Note 1.
