The XC6221B12BMR-G is a Low Dropout Regulator (LDO) in a SOT-25R package, manufactured by Torex Semiconductor. This LDO provides an output voltage of 1.2V, a maximum output current of 100mA, and enables a wide input voltage range of 2.4V-15V. This part features low power consumption, low-dropout voltage, and a fast transient response to allow for a stable supply current to the circuit. It also has a built-in over-current protection, thermal shutdown protection, and reverse voltage protection. Additionally, the XC6221B12BMR-G is RoHS compliant, making it an ideal choice for applications that require increased power efficiency.
