Application & Notes
TPS51285ARUKT by Texas Instruments is a Step-Down (Buck) Synchronous (2), Linear (LDO) (2) IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to N/A, output adjustable. The 20-WFQFN 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.
