A linear voltage regulator is a device used to maintain a constant voltage output. The MC7812ABT regulator is a three-terminal voltage regulator designed to provide a fixed regulated output of 12V. It offers an output current of up to 1.5A and features a low dropout voltage which minimises power dissipation.

The MC7812ABT linear regulator employs a pass transistor, one or more resistors and a zener diode that serves as a reference voltage. The reference voltage input is compared to the feedback voltage (Vout) and the difference between these two voltages is used to determine the control voltage for the pass transistor to maintain the output voltage (Vout) at the desired and regulated level. The pass transistor amplifies the voltage differences, and therefore, the regulated output voltage is regulated by controlling the amount of current it passes.

The MC7812ABT is used in a wide range of applications, including automotive, industrial and consumer applications. The regulator integrates a thermal shutdown circuit and reverse-battery protection to protect the regulator and the circuit it is used in. It also features a voltage-trim feature that enables fine tuning of the output voltage.

The MC7812ABT is designed to provide a constant output voltage at a wide range of operating temperature and input voltage conditions. It is capable of operating over a wide input voltage range of 4.32V to 32V, and a temperature range of -40C to 85C. The regulator is capable of delivering output current up to 1.5A, and its low dropout voltage minimises power dissipation, ensuring consistent performance and reliability.

The MC7812ABT is available in a variety of different packages, including 8-pin plastic dual-in-line package (PDIP), 8-pin plastic surface-mount package (SOIC) and 8-pin plastic small outline package (TSOP). It is fully compatible with EIAJ standards and meets all the requirements of UL1493 and EMC directive. Additionally, the MC7812ABT is 100% tested for quality and reliability.

The MC7812ABT linear regulator is an ideal choice for a wide range of applications that require a fixed and regulated voltage output. It is highly efficient and reliable, with excellent temperature stability, and is easy to install and maintain. Additionally, its versatile package options and wide operating temperature and input voltage ranges make it a perfect choice for a variety of projects.
