The XC6221B2527R-G is a Low Dropout Regulator (LDO) manufactured by Torex Semiconductor. This LDO is delivered in USPN-4 surface mount packaging, and is RoHS compliant. It has a dropout voltage of only 0.25V, and provides a regulated output voltage range of 1.3 to 15V. It supports maximum output currents up to 3A, and can operate with supply voltages as low as 1.8V. The XC6221B2527R-G also features built-in overcurrent protection, overvoltage protection, and overtemperature protection. Additionally, its on-chip resistor sets enable easy level setting without the need of external components. It is ideal for applications that require high accuracy, low thermal resistance, and low power dissipation.
