TI’s terms “Lead-Free” or “Pb-Free” mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0. TI bases its knowledge and belief on information provided by third parties, and makes no representation or warranty as ddatasheet the accuracy of such information.

Samples may or may not be available. Electrical specifications do not apply km78l12acz operating the device outside of its stated operating conditions. Efforts are underway to better integrate information from third parties.

TI has discontinued the production of the device. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. TI has taken and continues to take reasonable steps to provide representative and accurate information but may not have conducted destructive testing or chemical analysis on incoming materials and chemicals.

Documents Flashcards Grammar checker. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications.


The voltages available allow the LM78LXX to be used in logic systems, instrumentation, HiFi, and other solid state electronic equipment. This component has a RoHS exemption for either 1 lead-based flip-chip solder bumps used between the die and package, or 2 lead-based die adhesive used between the die and leadframe. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof.

Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer’s risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. Current limiting is included to limit the peak output current to a safe value.

Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release. With adequate heat sinking the regulator can deliver mA output current. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used.

Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices.
