Application & Notes
L4975A by STMicroelectronics is a Buck IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 50V, output 5.1V. The Multiwatt-15 (Vertical, Bent and Staggered Leads) package with surface mount mounting is standard for compact designs. Pay attention to input/output capacitor selection and PCB layout — switching regulators are sensitive to trace inductance.
