Fixed 2.1V rail at 500 mA — 3 MHz switching keeps the inductor small
The TPS62234DRYR is a fixed-output step-down buck regulator from Texas Instruments delivering 500 mA continuous current at a regulated 2.1V output. Input voltage range spans 2.05V to 6V, making it suitable for single-cell Li-ion or 3.3V/5V rails. The integrated synchronous rectifier boosts efficiency at light loads — a practical advantage for battery-powered gear where quiescent current matters.
Temperature grade and package — board-level fit for tight spaces
The 6-SON package measures 1.45x1 mm — a 0.5 mm pitch land pattern that demands careful solder-paste stencil design but rewards with minimal board real estate. The 6-UFDFN package (Supplier Device Package 6-SON) is a leadless, thermally enhanced DFN with an exposed pad.
Active production — sourcing posture and package options
ROHS3 compliant. The base product number TPS62234 covers multiple fixed-output voltage options; confirm the 2.1V variant (DRYR suffix) matches your rail requirement.
