SG7915AK-883B Voltage Regulators: Application Field And Working Principle

The SG7915AK-883B Voltage Regulator is part of the family of linear voltage regulators, known for its efficient, low-power performance, and easy-to-use design. This regulator is widely used in a diverse range of applications, from environmental monitoring and medical, to aviation and automotive electronics.

The SG7915AK-883B is a medium-power integrated circuit (IC) voltage regulator, designed by ON Semiconductor Corporation, that offers a series of features that make it highly suitable for a wide range of applications. It offers three adjustable output voltage levels, including the standard 5V, 3.3V and 1.8V, as well as adjustable soft-start and overvoltage protection.

The regulator is designed to operate over a wide range of input voltages, from 10V to 36V, while keeping its output voltage regulated according to the setting of the on-board regulator. It is also able to provide an output current of up to 500mA and a peak current of up to 1.5A.

The SG7915AK-883B is powered by a built-in linear voltage regulator architecture, which offers several advantages over other types of voltage regulators. Compared to switching regulators, the linear voltage regulator is able to maintain a steady output voltage in a much more efficient manner, allowing the user to save on power consumption and the cost of components. Additionally, the linear architecture can be programmed to maintain a constant voltage to the load, no matter what the input voltage is.

The SG7915AK-883B is comprised of an input voltage regulator, an output voltage regulator, an error amplifier and a voltage reference. The input voltage regulator, which receives the input voltage from the power source, is responsible for maintaining the desired input voltage for the circuit. The error amplifier is responsible for monitoring the output voltage, which can be varied depending on the voltage setting of the user, and compares it to the reference voltage set by the voltage reference. If the output voltage is too low or too high, the error amplifier will send a signal to the input regulator to adjust the input voltage accordingly in order to keep the output voltage regulated.

The SG7915AK-883B offers several protection features that make it a force to be reckoned with in commercial and industrial applications. Over-voltage protection limits the output voltage in case of an input voltage that is too high, while over-current protection shuts down the regulator when the output current exceeds the maximum value. The soft-start feature prevents sudden surges in output current, while the thermal shutdown feature shuts down the regulator when the die temperature of the IC becomes too high.

The SG7915AK-883B is ideal for applications such as automotive voltage regulators, TV protectors, LED lighting, medicine dispensing systems, telecommunications, motor control systems and so on. This IC can easily be incorporated into a wide range of applications, thanks to its flexible architecture, robust protection features and easy-to-use design.
