Introduction to PMIC - Voltage Regulators - Linear

PMIC, or power management integrated circuit (IC), is a type of integrated circuit (IC) responsible for regulating power in a system or circuit. It typically controls elements such as power supply voltages, currents, clock speeds and other various peripheral components. Voltage regulators are a type of PMICs that are used to regulate the output voltage of a power supply to an optimal level. Linear voltage regulators are one of the most widely used types available, as they are more cost-effective than other voltage regulation solutions, such as switching regulators.The S-1142A40H-E6T2U is a linear voltage regulator designed for a wide range of applications, including consumer electronics, automotive and industrial applications.
