Application & Notes
B5973DTR by STMicroelectronics is a Buck IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 36V, output 1.235V. The 8-SOIC (0.154", 3.90mm Width) Exposed Pad 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.
