XC6220B331MR-G 1A LDO VOLTAGE REGULATOR IC SOT-23-5

The XC6220B331MR-G is a low-dropout voltage regulator (LDO) manufactured by Torex Semiconductor. The Output voltage XC6220B331MR-G is selectable in 0.05V increments within the range of 0.8V~5.0V, using laser trimming technologies. An over current protection circuit and a thermal shutdown circuit are built in. The over current protection circuit will operate when the output current reaches its limit current. The thermal shutdown circuit will operate when the junction temperature reaches its limit temperature.

The XC6220B331MR-G LDO is a highly accurate, low noise, high speed, low dropout, and large current CMOS voltage regulator with Green Operation function. The XC6220B331MR-G consists of a voltage reference, an error amplifier, a current limiter, an inrush current prevention circuit and a phase compensation circuit plus a driver transistor.

With a 0.2Ω on-resistance driver transistor integrated, the ultra low dropout voltage performance with output currents up to 1A greatly extends battery life as does the Green Operation function which can switch between high speed and power save modes automatically. A low ESR ceramic capacitor can be used for the output stabilization capacitor (CL).
