Application & Notes
L387AH by STMicroelectronics is a power conversion IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 26V, output 5V. The Pentawatt-5 (Horizontal, 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.
