The SG7805AK is a linear voltage regulator that is part of a Compact Toroidal Regulated Switching Regulator (CTSR) family. It offers a wide input voltage range and a wide operating temperature range. It can be used to provide regulated voltage to a variety of electronic systems, including consumer electronics, medical and industrial electronics, automotive electronics and other specialized applications. The SG7805AK is a low-power linear regulator that is especially well suited for portable, low-power devices. The SG7805AK is a three-terminal, adjustable voltage regulator that can provide a regulated voltage of up to 1.3volts. Its output voltage is set with an external resistor network. It is designed to regulate output voltages over a wide temperature range and provide safe operation within its rated operating temperature range. Its power stage is suitable for applications that require up to 1.8amps. Its operating current range from 250microamps to 1.8amps. In addition to its linear regulation, the SG7805AK also features several advanced features, including thermal overload protection, output voltage trim, and an open-drain reset signal. It also has an inherent protection mechanism against overload and short-circuit failures. The device also features a low quiescent current (<10uA), which helps to minimize power drains.The working principle of the SG7805AK is based on a buck-type topology. It is composed of a low-power buck regulator, a high-efficiency MOSFET switch, and a voltage setting network. The buck regulator controls the MOSFET switch with a control signal that is generated from a voltage setting network. The voltage setting network sets the output voltage levels, and it is composed of an external resistor divider, a reference voltage, and an error amplifier. When the input voltage is higher than the output voltage, the buck-type regulator will enable the MOSFET switch and the output voltage is set according to the voltage setting network. When the input voltage is lower than the output voltage, the buck regulator will disable the MOSFET switch and the output voltage drops accordingly. The ON/OFF switch is controlled by the error amplifier, and it is triggered when the input voltage differs more than a specified amount from the output voltage. The SG7805AK is thus an excellent choice for applications that require precise and reliable voltage regulation. Its features make it especially suitable for portable and low-power applications, as well as applications that require thermal and overload protection. As such, it can be used in a wide range of applications, including consumer electronics, medical, industrial, automotive, and other specialized applications.
