The 6 V maximum input limits it to low-voltage supplies — not for 12 V or 24 V industrial rails. The 500 mA output ceiling covers small MCU cores, sensor transmitters, and Bluetooth/Wi-Fi modules; anything above that needs a higher-current sibling in the TPS6223x family. The 2 MHz switching also pushes ripple into a band that is easier to filter with small ceramics. ## Temperature grade and package — where it fits physically The 6-UFDFN package (1.45 mm x 1 mm) is a tiny SON with a centre pad for thermal dissipation; the board layout must match the recommended land pattern in the datasheet to avoid solder bridging and ensure adequate heat transfer. The base product number TPS62237 covers multiple output voltage options and package variants; the DRYR suffix identifies the 6-UFDFN tape-and-reel variant.","metaTitle":"TPS62237DRYR Step-Down Converter, 3.3 V Fixed, 500 mA","metaDescription":"Texas Instruments TPS62237DRYR buck converter: 2.05 V to 6 V input, fixed 3.3 V output at 500 mA, 2 MHz switching, -40°C to 125°C.
