SG7812K is a high voltage and low dropout (LDO) linear regulator with output voltage adjustable from 1.5V to 20 V. The device is equipped with a built-in regulator, a bandgap reference and other features that make it an ideal choice for power supply design.SG7812K is a low-noise device that has low quiescent current and is capable of providing up to 1.2A of output current. SG7812K is also designed to be stable over a wide range of operating conditions and offers protection against short-circuits, over-voltage and over-temperature conditions. Additionally, it has a wide input voltage range, and a high efficiency which makes the device suitable for a variety of applications.
In terms of its application fields, SG7812K can be used in a wide range of applications such as telecommunications, automotive, industrial and medical systems, where a stable voltage supply is desired. It can also be used to convert unregulated DC power into a regulated DC voltage when an adjustable voltage is not required. Furthermore, SG7812K is suitable for battery-powered systems, such as notebook computers and equipment with limited space available for power supply design.
The working principle behind SG7812K is based on the standard LDO regulators. When the input voltage is higher than the required output voltage, a portion of the voltage is dropped across the internal P-channel MOSFET, allowing a regulated output voltage. The device has a minimum dropout voltage of 0.6V, ensuring a stable and accurate output voltage as long as the minimum input voltage is greater than 1.05V greater than the output voltage.
The device has an internal bandgap reference of 1.230V which is used to control the output voltage and a current mirror circuit which aids in controlling the voltage drop across the P-channel MOSFET. The current mirror circuit also ensures that the output voltage remains constant at the desired value, even when there is a change in the input voltage or output current.
SG7812K also has a built-in thermal shut-down feature. This feature can protect the device from over-temperature conditions, providing reliable and stable operation. Additionally, the device is equipped with under-voltage lockout, over-voltage protection and output current short circuit protection, allowing it to operate even in harsh operating environments.
In conclusion, SG7812K is a high voltage and low dropout (LDO) linear regulator with adjustable output voltage from 1.5V to 20V. Its built-in regulators, bandgap reference and other features make it an ideal choice for power supply design. In addition, it is suitable for a variety of applications, has a wide input voltage range and offers good efficiency. It also has a number of protection features for added reliability.
