Integrated Circuit
Positive 3 Terminal Voltage Regulator, 100mA
Description:
The NTE981 is a positive 3–terminal voltage regulator available in a TO92 type package. With ade-
quate heat sinking this device can deliver 100mA output current. Current limiting is included to limit
peak output current to safe value. Safe area protection for the output transistors is provided to limit
internal power dissipation. If internal power dissipation becomes too high for the heat sinking pro-
vided, the thermal shutdown circuit takes over preventing the IC from overheating.
When used as a zener diode/resistor combination replacement, the NTE981 usually results in an ef-
fective output impedance improvement of two orders of magnitude, and lower quiescent current.
These regulators can provide local on card regulation, eliminating the distribution problems
associated with single point regulation. Typical applications include use in logic systems, instrumen-
tation, HiFi, and other solid state electronic equipment. Although designed primarily as fixed voltage
regulator this device can be used with external components to obtain adjustment voltages and cur-
rents.
