XC6220 Series ETR0341-015 1A LDO Voltage Regulator with Green Operation Green Operation-Compatible GENERAL DESCRIPTION The XC6220 series is a highly accurate, low noise, high speed, low dropout, and large current CMOS voltage regulator with Green Operation function. The series 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 0.2 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 (C ). L Output voltage 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 inrush prevention circuit works by controlling the inrush current which charges to CL when the IC starts up. In this way, voltage fluctuations in power supply caused by inrush current during system start up can be minimized. The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power consumption.
