PMIC (Power Management Integrated Circuits) are integrated circuits used to control and manage power in a given system. As such, they offer a range of features, such as the ability to adjust the output voltage, regulate current and monitor and control various aspects of power supply and usage. Voltage regulators are one of the key components in a PMIC, controlling and regulating the voltage of the system. Linear voltage regulators are popular voltage regulators due to their ability to regulate voltage with minimal complexity and cost. The SG137K-DESC is a linear voltage regulator which is designed to deliver superior performance, stability and reliability. This article will provide a detailed overview of the application field and working principle of the SG137K-DESC.
