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.","metaTitle":"TPS62203DBVR TI Buck Regulator 3.3V 300mA SOT-23-5","metaDescription":"Texas Instruments TPS62203DBVR step-down buck regulator, fixed 3.3V output, 300mA, 1MHz switching, SOT-23-5.
