The XC6223T391GR-G is a 300mA high speed low dropout (LDO) regulator manufactured by Torex Semiconductor. It is a "nanopower" series regulator available in a small chip size package that offers high efficiency, low power, wide temperature range, and low quiescent current (Iq). It also features an "Ultra Low Dropout Voltage" mode that enables greater current stability than conventional regulators. The XC6223T391GR-G is ideal for power supply applications that require high efficiency and low power consumption in a small size. Its operating voltage range is from 2.5V to 5.5V, with output voltage of 1.2V up to 4.6V. It is a low noise, low ripple and fast transient response regulator that can offer up to 300mA of current and is suitable for a wide range of applications such as automotive, consumer, computer, and industrial.
