The XC6223T331GR-G is a Low Dropout (LDO) Voltage Regulator manufactured by Torex Semiconductor. This LDO Voltage Regulator 300mA High Speed LDO Regulator is a highly precise low-noise linear power supply IC that can handle up to 300mA of load current and provide a high-speed, low-dropout voltage regulation of 1.0% from 1.8 to 6.5V. This regulator also uses an ultra-low noise bulk-capacitor which absorbs unwanted switching noise and produces high-quality output noise. Additionally, it features a low-IQ operation, highly accurate voltage reference, low-temperature drift, and programmable between 1ms and 3.8ms soft-start time. This part also has over-current protection and an internal thermal protection circuit to protect against damage due to excessive power dissipation. Other features include wide temperature range from -40 to +85 temperature, package size of 0.5mm x 0.5mm x 0.35mm, and a fast response time of 30µs. This LDO Voltage Regulator is suitable for applications in mobile phones, digital camera, and other portable media devices.
