The LM79L12ACM is a linear voltage regulator manufactured by Texas Instruments. It is part of the wide range of voltage regulators offered by TI, and it can be used in a variety of applications and environments. The LM79L12ACM is a 3-terminal, positive voltage regulator featuring wide input voltage range, internal thermal overload protection, and on-chip regulation. It is intended for use in applications requiring a constant output over a wide input range.

The LM79L12ACM\'s application field covers general-purpose usage, such as computers, portable devices, and automotive applications. This device features a high current capability, low dropout voltage, and a very low noise voltage regulator. It also offers protection against transient overvoltage and thermal overload.

The LM79L12ACM is designed to regulate an input supply voltage between 4.75V and 30V and output voltage between 3V and 25V, with a maximum output current of 2A. This regulator requires a minimum input voltage of at least 1.5V greater than the target output voltage. It also has a maximum quiescent current of 4mA at a full 1A output current.

The LM79L12ACM also offers on-chip protection for overload and thermal regulation, making it suitable for applications with high current requirements and/or which must operate in an environment with high temperature and ambient noise.

On the other hand, the LM79L12ACM features an internally set output voltage of 5.0V, 7.8V and 12V, with low output noise levels less than 3mV p-p. This makes it an ideal choice for applications that need a precision output voltage.

The LM79L12ACM can operate in one of two modes. In standard mode, the regulator remains in regulation even with a short-circuit at the output; in cut-off mode, the regulator will stop regulating and the output will go to 0V. In both cases, the device is fully protected against input or output overloads or short-circuits.

The LM79L12ACM is a mainstay voltage regulator for many applications, due to its low dropout voltage, low quiescent current, low output noise, and on-chip protection for overload and thermal regulation. It offers a wide input voltage range and a superior output regulation, making it an excellent choice for many applications.
