XC6228

XC6228 Series 300mA High Speed LDO Regulator with ON/OFF Switch ETR03116-001a ■GENERAL DESCRIPTION The XC6228 series is a high speed LDO regulator that features high accurate, low noise, high ripple rejection, low dropout and low power consumption. The series consists of a voltage reference, an error amplifier, a driver transistor, a current limiter, a phase compensation circuit. The CE function enables the circuit to be in stand-by mode by inputting low level signal. In the stand-by mode, the series enables the electric charge at the output capacitor CL to be discharged via the internal switch, and as a result the VOUT pin quickly returns to the VSS level. The output stabilization capacitor CL is also compatible with low ESR ceramic capacitors. ■APPLICATIONS ● Mobile devices ● Wireless communications ● Modules ● Mobile phones ■FEATURES Maximum Output Current Input Voltage Range Output Voltages Dropout Voltage Low Power Consumption Stand-by Current High Ripple Rejection Protection Circuits : 300mA : 1.6V ~ 5.5V : 1.2V ~ 4.0V (Accuracy ±2%) 0.1V increments : 200mV＠IOUT=300mA (VOUT=3.0V) : 100μA : 0.1μA : 80dB＠f=1kHz : Current Limit (400mA) Low ESR Capacitors : CIN=1μF, CL=1μF CE Function : Active High, CL High Speed Discharge Operating Ambient Temperature : -40℃ ~ 85℃ Small Package : USPQ-4B04 Environmentally Friendly : EU RoHS Compliant, Pb Free ■TYPICAL APPLICATION CIRCUIT ■ TYPICAL PERFORMANCE CHARACTERISTICS ●Load Transient Response VIN CIN =1μF (ceramic) ...
