The XC6221A122MR-G is an SOT-25 RoHS-compliant Low Dropout Regulator (LDO) manufactured by Torex Semiconductor. It is a voltage regulator designed to provide a stable output voltage with low dropout voltage, high accuracy, low quiescent current, and good line regulation. Its full product name is XC6221A122MR-G SOT-25 RoHS Low Dropout Voltage Regulator. This LDO regulator is designed to be used in a wide range of applications such as mobile phones, digital cameras, portables, PDAs, and other consumer electronic components. It features an output current of either 500mA or 1A depending on the version, a maximum dropout voltage of just 1.23V, and an output voltage adjustable range of 1.2V - 5.5V. The XC6221A122MR-G provides tight regulation with a line regulation of 0.04%, a load regulation of 0.08%, and a low temperature coefficient of 10ppm/C. It also features high ripple rejection and is highly efficient with a low quiescent current of only 10uA typ. The XC6221A122MR-G is available in an SOT-25 package and is lead free and RoHS compliant.
