L78L12ACZ-TR Integrated Circuits (ICs)

The L78L12ACZ-TR is a linear voltage regulator. It was originally developed to help managers of portable electronic device designs in providing dependable, cost-effective, and low-noise solutions. Especially when the device is powered by different kinds and wide voltages of energy sources. This type of regulator has become the industry standard for a long time, and is offered in a wide range of versions.

The L78L12ACZ-TR is a three-terminal regulator with adjustable output. It is available in an SOT-89 plastic package, as well as an industry standard version that can operate up to 40V and 12A. The device can be used in a variety of applications, including portable audio, automotive and home appliances, microprocessors, e-health, and computers. The output current is adjustable with external components, and the input voltage can be up to 40V.

To understand how this regulator works, it is important to review the design principles of linear voltage regulation. Generally, these regulators use a linear series regulator and include an internal feedback circuit that controls the output voltage based on the changes in the output voltage of the power source. With this type of regulator, the output voltage stays essentially the same when the input voltage changes. The regulator controls the output voltage using transistors to regulate the results.

The L78L12ACZ-TR follows this design principle. It is equipped with an adjustable output voltage through an internal voltage reference. The device also features precise current limiting and thermal protection against overloading. Additionally, the power dissipated in the regulator is minimal because of its low Drop-Out voltage, which helps save energy.

The L78L12ACZ-TR also has some other features that make it suitable for a wide range of applications. For example, the regulator is equipped with an adjustable input voltage, so it can be used with a variety of power sources. It also offers high accuracy and is able to maintain voltage regulation even when the input voltage changes. Finally, the device is compatible with a plethora of components, making it easier to customize the regulator according to a particular use.

In summary, the L78L12ACZ-TR is a linear voltage regulator designed to provide reliable and cost-effective solutions for a wide range of applications. It features an adjustable output voltage, precise current limiting, thermal protection, and low Drop-Out voltage. The device also offers compatibility with a variety of components and adjustable input voltage. Thanks to these features, the L78L12ACZ-TR is a go-to choice for most applications that require a voltage regulator.
