The XC6220B251MR-G is a 1A high speed Low DropOut (LDO) voltage regulator manufactured by Torex Semiconductor. It is designed to have low quiescent current and output noise performance at high switching speeds. It features a "green" operation which allows the regulators to optimize efficiency for lowest power consumption. It is housed in an MSOP8 package and it has an output voltage accuracy of +/-2%, a temperature range of 0°C to +85°C, and a maximum input voltage of 16V. It also has built-in protection for current-limit protection, over-temperature protection, and over-voltage protection. This regulator is suitable for use in automotive, home appliance, portable device, smart phone, and point-of-load DC/DC regulators.
