The fixed 3.3 V output is set internally — no external resistor divider, so the output accuracy depends only on the internal reference. At 300 mA continuous output, the 1 MHz switching rate keeps the inductor value in the 4.7 µH to 10 µH range, which fits the SOT-23-5 footprint without crowding the passives. ## Temperature grade and package — where it goes The Tape & Reel (TR) delivery is the standard shipping medium for automated pick-and-place assembly.","metaTitle":"TPS62203DBVTG4 Buck Converter, 3.3V Fixed Output, 300mA","metaDescription":"Texas Instruments TPS62203DBVTG4 step-down buck converter: 2.5V-6V input, fixed 3.3V output, 300mA, 1MHz switching, synchronous rectifier.
