XC6221B122MR-G

XC6221 Series ETR0328_015 ■GENERAL DESCRIPTION The 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. Output voltage is selectable in 0.05V increments within a range of 0.80V~5.00V, using the laser trimming technology set in factory. The current limiter's fold-back circuit also operates as a short circuit protection and an output current limiter at the output pin. The series achieves a fast response with only 25μA of low power consumption. Also the series has low dropout voltage characteristics, which is 80mV at IOUT=100mA and VOUT=3.0V. With the use of small USP-4 and ultra small USPN-4 packages, a small footprint circuit can be designed. ■APPLICATIONS ■FEATURES ●Smart phones / Mobile phones Maximum Output Current Dropout Voltage Operating Voltage Range Output Voltage Range Accuracy ●Portable game consoles ●Digital still cameras / Camcorders ●Digital audio equipments ●Mobile devices / terminals Low Power Consumption Stand-by Current High Ripple Rejection CE Function : 200mA : 80mV@ IOUT=100mA,VOUT=3.0V : 1.6V ~ 6.0V : 0.80V~5.00V (0.05V increments) : +2% (VOUT >1.50V) (Standard) +30mV (VOUT≦1.45V) (Standard) +1% (VOUT >2.00V) (High Accuracy) +20mV (VOUT≦1.95V) (High Accuracy) : 25μA (TYP.) : Less than 0.1μA : 70dB @ 1kHz : CE Active High Standby current below 0.1μA CL High-Speed Auto-Discharge (XC6221B/D) CE Pin internally pulled-down (XC6221C/D) : 1.0μF ceramic capacitor Low ESR Capacitor Low Output Noise Operating Ambient Temperature : -40℃~+85℃ Packages : USP-4, SOT-25, SSOT-24 USPN-4 : EU RoHS Compliant, Pb Free Environmentally Friendly ■ TYPICAL PERFORMANCE CHARACTERISTICS ●Load Transient Response 1.9 XC6221x182 VIN=VCE=2.8V , Tr=Tf=5μs Ta=25℃ , CIN=CL=1.0μF (ceramic) 300 1.8 250 1.7 200 1.6 1.5 150 100mA Output Current 100 1.4 Output Current: I OUT (mA) Output Voltage Output Voltage: VOUT (V) ■TYPICAL APPLICATION CIRCUIT 50 10mA 1.3 0 Time: (500μs/div) 1/28 XC6221 Series ■PIN CONFIGURATION VSS 2 3 CE VOUT 1 4 VIN VOUT NC 5 4 1 2 3 VIN VSS CE USP-4 (BOTTOM VIEW) SOT-25 (TOP VIEW) VSS 2 3 CE VOUT 1 4 VIN VIN VOUT 4 3 1 2 CE VSS SSOT-24 (TOP VIEW) *It is recommended that the heat dissipation pad of the USP-4 package is soldered by using the reference mount pattern and metal mask pattern for mounting strength.
