Getting 1 A out of this footprint class is the part's main appeal: it packs high-current linear regulation into a space normally reserved for 150–300 mA parts, which helps compact IoT modules, battery chargers, set-top boxes, and handheld devices avoid the board area of a larger SOT-223 or DPAK regulator. The maximum input is 6 V — sized for a single Li-ion cell or a clean 5 V rail — and maximum dropout is 0.655 V at 1 A, so a 4.2 V end-of-charge cell still leaves roughly 3.5 V at the pin before the output starts to fall out of regulation. Torex markets the family as \"green operation,\" and the 18 µA quiescent current keeps the always-on draw modest for a 1 A part, with a maximum supply current of 108 µA. An enable pin provides on/off control for power sequencing or sleep gating, and protection covers over-current and over-temperature. Note the temperature envelope: the XC6220B331MR-G is specified for -40 °C to 85 °C, narrower than the 125 °C typical of many LDOs, so it fits consumer and commercial equipment well but should be checked against extended-range or industrial applications. PSRR is 50 dB at 1 kHz — fine for digital and interface rails, less suited to precision analog. When selecting, verify the SOT-25-5 thermal capability for sustained 1 A in your board stack, keep the 6 V input ceiling and the 85 °C limit in the budget, and the fixed 3.3 V output removes any adjustment network from the BOM.","metaTitle":"XC6220B331MR-G Torex 3.3V 1A LDO Linear Regulator SOT-25","metaDescription":"Torex XC6220B331MR-G 3.3 V / 1 A CMOS LDO, -40~85 °C, SOT-25-5.
