Nonetheless, such components are subject to these terms. If internal power dissipation becomes too high for the heat sinking provided, the thermal shutdown circuit takes over preventing the IC from overheating. TI is not responsible or liable for such altered documentation. The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. Information of third parties may be datasheer to additional restrictions.

Variable Output Regulator 0. Products conform to specifications per the terms of the Texas Instruments standard warranty. These regulators can provide local on card regulation, eliminating the distribution problems associated with single point regulation. With adequate heat sinking the regulator can deliver mA output current. Samples may or may not be available.

No TI components are authorized for use in FDA Class III or similar life-critical medical equipment unless authorized officers of the parties have executed a special agreement specifically governing such use.

TI is not responsible or liable for any such statements. Popular tags for this: Not recommended for new designs.
