The MC79L12ACPRAG voltage regulator, a member of the MCOU family of linear voltage regulators, provides reliable and cost-effective, local on-board regulation of the power supply. It can be used to supply a wide range of current and accuracy requirements across a variety of applications.

The MC79L12ACPRAG is an adjustable output regulator, with an adjustable output voltage range from 2V to 12V in incremental steps of 1.25V. It uses a PWM mode of control, preventing large output voltage spikes when the load changes due to dynamic operation. The MC79L12ACPRAG has a maximum operating temperature of 125°C, and a maximum output current of 1A.

The MC79L12ACPRAG is suitable for use in a wide range of power applications, particularly those which require stable current regulation in the presence of varying output voltage load. Examples include automotive and industrial motor control systems, lighting and high-speed switching applications, and medical equipment.

The MC79L12ACPRAG works by using a pair of PNP and NPN bipolar transistors to form a floating, current-regulating circuit. The output voltage is adjusted by a variable resistor connected to the base of an NPN transistor. This control causes the current through the PNP and NPN transistors to change as the output voltage varies, resulting in an output voltage that is kept close to the set point.

The MC79L12ACPRAG is further equipped with a wide range of protection features to ensure safe and reliable operation. These include protection against over-voltage, over-current, reverse polarity and over-temperature. The device also has safeguards against short circuits and open circuits, as well as transient protection during startup and shutdown.

The MC79L12ACPRAG offers a high degree of design flexibility and is an ideal choice for a variety of voltage regulation applications. Its high efficiency, wide operating temperature range and extensive protection capabilities make it well suited for many applications. Additionally, its small footprint and low profile make it an attractive choice for embedded systems.

The MC79L12ACPRAG is suitable for a wide variety of applications, from automotive and industrial motor control systems to lighting and switching applications, medical equipment and more. Its wide range of features make it an ideal choice for reliable, cost-effective voltage regulation.
