NTE1979
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 = +25°C unless otherwise specified)

Note 2. The specified condition TJ = +25°C means that the test should be carried out with the test
time so short (within 10ms) that the drift in characteristic value due to the rise in chip junction
temperature can be ignored.
