XC6222

XC6222 Series 700mA High Speed LDO Regulator ETR03044-009b ■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. ■APPLICATIONS ● USB / HDMI products ● Optical disk drive ● Magnetic disk drive ● Smart phones / Mobile phones ● Portable game consoles ● Modules (wireless, cameras, etc. ) ● E-book Reader / Electronic dictionaries ■FEATURES Maximum Output Current Dropout Voltage Operating Voltage Range : 700mA : 120mV @IOUT=300mA (VOUT=3.0V) : 1.7V ~ 6.0V Output Voltage Accuracy : 0.8V~5.0V (0.05V increments) : +1% (VOUT＞2.0V) +0.02V (VOUT≦2.0V) Low Power Consumption : 100μA High Ripple Rejection : 65dB @ 1kHz Low ESR Capacitor : Ceramic capacitor Chip Enable...
