XC6222 Series ETR0344-008 700mA High Speed LDO Regulator GENERAL DESCRIPTION The XC6222 series is a highly accurate, low noise, high ripple rejection, low dropout, and low power consumption high speed voltage regulator. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a thermal protection circuit, and a phase compensation circuit. The CE function enables the entire circuit to be placed in a stand-by state by inputting a low level signal to the CE pin. In this stand-by mode, the electric charge at the output capacitor (CL) will be discharged by the internal auto-discharge switch, and as a result the VOUT pin will quickly return to the VSS level. Over-current protection and thermal protection circuits are integrated. The protection circuit starts to operate when either output current reaches the current limit level or junction temperature reaches the temperature limit.
