TO-92
Info as pdf-file
Description:
The NTE981 is a positive 3-terminal voltage regulator in a TO92 type package. With adequate heat sinking this device can deliver up to 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 provided, the thermal shutdown circuit takes over preventing the IC from overheating.
When used as a zener diode/resistor combination replacement, this device usually results in an effective output impedance improvement of two orders of magnitude, and lower quiescent current. The NTE981 can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Typical applications include use in logic systems, instrumentation, Hi-Fi, and other solid state electronic equipment. Although designed primarliy as a fixed voltage regulator, this device can be used with external components to obtain adjustment voltages and currents.
Features:
- Output Voltage Tolerances of ±5% over the Temperature Range
- Output Current of 100mA
- Internal Thermal Overload Protection
- Internal Short-Circuit Current Limiting
- Output Transistor Safe-Area Compensation
