Application & Notes
LF18CPT 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 16V, output 1.8V. The TO-252-5, DPak (4 Leads + Tab), TO-252AD 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.
