SG7815AT is a two-terminal, adjustable voltage regulator specifically developed for use in automotive electronic applications. This low dropout voltage regulator allows for a wider operating range and greater flexibility for automotive applications. SG7815AT is manufactured to meet the requirements of the automotive industry. It is designed to ensure that the operating range over which it will regulate is wider than the system voltage range and has a low operating temperature.

The application field of SG7815AT can be seen in automotive electrics and electronics, where the voltage regulation needs to be precise and accurate. Current applications in this field include but are not limited to Motor Control Units, Electric Power Steering, Vehicle Immobilisers, and Electronic Throttle Controls. Additionally, SG7815AT can be used in other systems that require reliable and precise voltage regulation, such as small household appliances, computers, and other consumer electronics.

The working principle of SG7815AT is based on the series pass architecture which consists of an easy to operate adjustable voltage reference, an error amplifier, and an internal NPN pass regulator. The internal pass regulator provides current to any load connected to its output and can deliver up to 1.5A of peak output current. The output is adjusted to the regulated voltage level by the voltage reference and the error amplifier. Additionally, SG7815AT provides a fixed output voltage option with a circuit bypass option which reduces the number of external components. The power dissipation rating is-0.6A and the input voltage range is 4.5V to 28V.

SG7815AT also features an active low enable control, providing mechanical and electrical isolation directly from the high side of the regulator. This high side isolation feature allows the device to be enabled/disabled without having to directly switch or control the output voltage level. An internal thermal shut down allows SG7815AT to protect itself from overtemperature situations, reducing the risk of damage to the device.

In summary, SG7815AT is a two-terminal, adjustable voltage regulator specifically developed for use in automotive electronic applications. With its series pass architecture, wide operating range and low dropout voltage, SG7815AT provides an ideal solution for those applications requiring reliable, precise and accurate regulation. SG7815AT also features built-in protection features such as thermal shut down and active low enable control to ensure the device operates safely and efficiently.
