The XC6220B381PR-G with Torex Semiconductor 1A High Speed LDO Regulator with "Green Operation" is a low dropout (LDO) Linear voltage regulator designed by Torex Semiconductor. It is designed with advanced CMOS process, providing ultra low quiescent current and many other features. This part offers very low dropout voltage of just 0.28 V at a low current of 1A in order to provide efficient power supply regulation. It also features built in overcurrent protection with foldback current-limit and thermal shutdown, to protect it from damage. Additionally, this part features a "green operation" mode which allows for improved power saving, higher system reliability and lower power consumption at light load conditions. All in all, this part provides high-speed, low noise, high-performance, stable, and efficient LDO regulation to ensure a reliable and stable power supply.
