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 V pin quickly returns to the V level. The output stabilization capacitor (C ) is also compatible with low ESR ceramic OUT SS L 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 I =100mA and V =3.0V. OUT OUT 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 : 200mA <Up to 250mA (TYP.)> Dropout Voltage : 80mV@ IOUT=100mA,VOUT=3.0V ●Portable game consoles Operating Voltage Range : 1.6V ~ 6.0V Output Voltage Range : 0.80V~5.00V (0.05V increments) ●Digital still cameras / Camcorders Accuracy : +2% (VOUT >1.50V) (Standard) +30mV (V ≦1.45V) (Standard) OUT +1% (V >2.00V) (High Accuracy) ●Digital audio equipments OUT +20mV (V ≦1.95V) (High Accuracy) OUT Low Power Consumption : 25μA (TYP.) ●Mobile devices / terminals Stand-by Current : Less than 0.1μA High Ripple Rejection : 70dB @ 1kHz CE Function : CE Active High Standby current below 0.1μA C High-Speed Auto-Discharge L (XC6221B/D) CE Pin internally pulled-down (XC6221C/D) Low ESR Capacitor : 1.0μF 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 ■ TYPICAL APPLICATION CIRCUIT ■TYPICAL PERFORMANCE CHARACTERISTICS ●Load Transient Response XC6221x182 VIN=VCE=2.8V , Tr=Tf=5μs Ta=25℃ , CIN=CL=1.0μF (ceramic) 1.9 300 Output Voltage 1.8 250 Output Voltage: V (V)OUT 111...567 100mA Output Current 112050000 Output Current: I (mA)OUT 1.4 50 10mA 1.3 0 Time: (500μs/div) 1/28

XC6221 Series ■OPERATIONAL EXPLANATION <Output Voltage Control> The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the V pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short protect circuit OUT operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the CE pin's signal. CE OCNo/nOtrFoFl VIN - CE CE/ + EArmropr CuLrimreitnt ceiraccuhit VOUT R1 Rdischg CE/ R2 RVefoelrteagnece VSS <Input and Output Capacitors> The XC6221 needs an output capacitor C for phase compensation. Values required for the phase compensation are L shown in the chart below. If a loss of the capacitance happens, the stable phase compensation may not be obtained. Please ensure to use a capacitor which does not depend on bias or temperature too much. For a stable power input, please connect an input capacitor CIN of 1.0μF between the VIN pin and the VSS pin. ●Except USPN-4 OUTPUT VOLTAGE (V) OUTPUT CAPACITOR VALUE 0.80V〜1.15V C ≧4.7μF L 1.20V〜1.35V C ≧2.2μF L 1.40V〜4.00V C ≧1.0μF L 4.05V〜5.00V C ≧2.2μF L ●USPN-4 OUTPUT VOLTAGE (V) OUTPUT CAPACITOR VALUE 1.20V〜4.00V C ≧2.2μF L 4.05V〜5.00V C ≧4.7μF L <C Auto-Discharge Function> L XC6221B/D series can discharge the electric charge in the output capacitor (C ), when a low signal to the CE pin, which L enables the whole IC circuit to be turned off, is inputted via the N-channel transistor and C auto-discharge resistance L (R ) located between the V pin and the V pin (cf. BLOCK DIAGRAM). The C auto-discharge resistance (R ) DCHG OUT SS L DCHG value is set at 780Ω(V =4.0V @ V =6.0V at typical). The discharge time of the output capacitor (C ) is set by the C OUT IN L L auto-discharge resistance (R ) and the output capacitor (C ). By setting the time constant of the C auto-discharge DCHG L L resistance value [R ] and the output capacitor value (C ) as τ(τ=C x R ), the output voltage after discharge via DCHG L L DCHG the N-channel transistor is calculated by the following formula.

XC6221 Series ■OPERATIONAL EXPLANATION (Continued) <Current Limiter, Short-Circuit Protection> The XC6221 series’ fold-back circuit operates as an output current limiter and a short protection circuit for the output pin. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. When the output pin is short-circuited to the V pin, the current falls and reaches about 30mA. SS <CE Pin> The XC6221 internal circuitry can be shutdown via the CE pin signal. In shutdown mode, output at the V pin will be OUT pulled down to the V level via R1 & R2. However, with the XC6221B/D series, the C auto-discharge resistor is SS L connected in parallel to R1 and R2 while the power supply is applied to the V pin. Therefore, time until the V pin IN OUT reaches the V level is shorter. For the XC6221A/B, the output voltage becomes unstable, when the CE pin is left SS open. For the XC6221C/D, the output voltage becomes V level because the CE pin is short-circuited to V via an SS SS internal pull-down resistor. However, the CE input current will be increased via a pull-down resistor when the IC operates. If this IC is used with the correct output voltage for the CE pin, the logic is fixed and the IC will operate normally. However, the supply current may increase as a result of shoot-through current in the IC's internal circuitry when a medium voltage is input. ■NOTES ON USE 1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please wire the input capacitor (C ) and the output capacitor (C ) as close to the IC as possible. IN L 3. Torex places an importance on improving our products and its reliability. However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment. 9/28
