Product details

Fixed 3.3V rail from a single inductor

The TPS62203DBVR is a fixed 3.3V output, 300 mA step-down buck regulator from Texas Instruments. Switching at 1 MHz allows the use of small, low-profile inductors — typically 4.7 µH or 10 µH — keeping the total solution footprint under 30 mm².

Input range and thermal envelope

The input voltage range spans 2.5V to 6V, covering single-cell Li-ion (3.0-4.2V) and regulated 5V rails. At full 300 mA load and 1 MHz switching, the junction temperature stays within the rated range with basic PCB copper area; no exposed pad is needed on the SOT-23-5 package.

Frequently asked questions

Can TPS62203DBVR be used in low-power applications?

Yes. The 300 mA output and 1 MHz switching make it suitable for battery-powered devices, IoT nodes, and portable instruments where efficiency and small size are priorities.
