XC6221B332MR

XC6221B332MR Description générale

■ GENERAL DESCRIPTIONThe XC6221 series is a high accuracy, low noise, high speed, low dropout CMOS regulator with high ripple rejection. The series includes a reference voltage source, an error amplifier, a current limiter, and a phase compensation circuit. The CE function enables the entire circuit to be in stand-by state by inputting low level signal. As for the XC6221B/D 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 quickly returns to the VSS level. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors.■ FEATURES Maximum Output Current : 200mA Dropout Voltage : [email protected] IOUT=100mA,VOUT=3.0V Operating Voltage Range : 1.6V ~ 6.0V Output Voltage Range : 0.80V~5.00V (0.05V increments) Accuracy : +2% (VOUT>1.50V) (Standard) +30mV (VOUT≦ 1.45V) (Standard) +1% (VOUT>2.00V) (High Accuracy) +20mV (VOUT≦ 1.95V) (High Accuracy)Low Power Consumption : 25μ A (TYP.) Stand-by Current : Less than 0.1μ A High Ripple Rejection : 70dB @ 1kHz CE Function : CE Active High Standby current below 0.1μ A CL High-Speed Auto-Discharge (XC6221B/D) CE Pin internally pulled-down (XC6221C/D) Low ESR Capacitor : 1.0μ F ceramic capacitor Low Output Noise Operating Ambient Temperature : -40℃ ~+85℃ Packages : USP-4, SOT-25, SSOT-24 USPN-4 Environmentally Friendly : EU RoHS Compliant, Pb Free■ APPLICATIONS● Cellular phones● Cordless phones● Wireless communication equipment● Portable games● Cameras, VCRs● Portable AV equipment● PDAs
