It is also possible to use the circuits as the control. National Semiconductor Electronic Components Datasheet. They are designed for local regulation on digital logic cards, eliminating the distribution problems association with single-point regulation. The devices are available in two standard transistor packages.

In the solid-kovar TO-5 header, it can deliver output currents in ex- cess of mA, if adequate heat sinking is provided. With the TO-3 power package, the available output current is greater than 1A.

Current limiting is included to limit the peak datasheeh current to a safe value. In addition, thermal shutdown is provided to keep the IC from overheating.

If internal dissipation becomes dstasheet great, the regulator will shut down to prevent excessive heating. Considerable effort was expended to make these devices easy to use and to minimize the number of external compo- nents.

It is not necessary to bypass the output, although this does improve transient response somewhat. Input bypass- ing is needed, however, if the regulator is located very far from the filter capacitor of the power supply. Stability is also achieved by methods that provide very good rejection of load or line transients as are usually seen with TTL logic. Although designed primarily as a fixed-voltage regulator, the output of the LM series can be set to voltages above 5V, as shown.
