Integrated Circuit

3–Terminal Positive Voltage Regulator

5V, 3A

Description:

The NTE931 is a 3–terminal fixed positive voltage regulator in a TO3 type package capable of driving

loads up to 3A. New circuit design and processing techniques are used to provide the high output

current without sacrificing the regulation characteristics of lower current devices.

This device is virtually blowout proof. Current limiting and thermal shutdown provide a high level of

reliability. No external components are required for operation of the NTE931, however, if the device

is more than 4 inches from the filter capacitor a 1µF solid tantalum capacitor should be used on the

input. A 0.1µF or larger capacitor may be used on the output to reduce load transient spikes created

by fast switching digital logic, or to swamp out stray load capacitance.

An overall worst case specification for the combined effects of input voltage, load current, ambient

temperature, and power dissipation ensures that the NTE931 will perform satisfactory as a system

element.

Note 1. Without a heatsink, thermal resistance is about 35°C/W. With a heatsink, the effective thermal

resistance can only approach the specified value of 2°C/W, depending on the effeciency of the

heatsink.
