LM80LM79

LM80LM79 is a designation for a series of solid-state voltage regulators produced by National Semiconductor. The company, which was founded in 1959, was known for its high-performance analog integrated circuits and was acquired by Texas Instruments in 2011.

The LM80 series of voltage regulators was designed to provide a stable and efficient means of regulating the voltage supply to electronic circuits. These regulators use a linear control circuit to maintain a specified output voltage, despite changes in input voltage or load current.

The LM79 series of regulators are similar to the LM80 series, but are designed to operate with a higher input voltage and are often used in circuits that require a higher voltage supply. Both the LM80 and LM79 series of regulators were widely used in a variety of applications, including audio equipment, medical devices, and power supplies.

Some key characteristics of the LM80 and LM79 series of regulators include their ability to provide a high level of voltage regulation, their low dropout voltage, and their high current handling capability. These regulators are also known for their high reliability and long lifespan, making them suitable for use in a wide range of industrial and commercial applications.

The LM80 and LM79 series of regulators are still available for purchase from several sources, including surplus electronics retailers and on-line marketplaces. However, many of the original components have been discontinued and are no longer available from National Semiconductor or its distributors.
