XC6420 Series ETR0352-008 150mA Small Dual LDO Regulator with ON/OFF Switch ■GENERAL DESCRIPTION The XC6420 series is a small dual CMOS LDO regulator with 2-channel 150mA outputs. The series features high speed, high accuracy, high ripple rejection and low dropout voltage. The series is capable of high density board installation by the small package of two low on-resistance regulators. Each output voltage is internally set in a range from 1.2V to 3.6V in increments of 0.05V with ±2% accuracy. The EN function controls the two regulators on/off independently. In the stand-by mode, the electric charge at the output capacitor CL is discharged via the internal switch and as a result the VOUT pin quickly returns to the VSS level. The series is also compatible with low ESR ceramic capacitors. The high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance. The two regulators are completely isolated so that a cross talk during load fluctuations is minimized. ■APPLICATIONS ● Smart phones / Mobile phones ● Portable game consoles ● Digital audio equipments ● Digital still cameras / Camcorders ■FEATURES Maximum Output Current Operating Voltage Range Output Voltage Dropout Voltage Low Power Consumption Stand-by Current Ripple Rejection EN Function Protection Circuit Output Capacitor Operating Ambient Temperature Packages Environmentally Friendly ■TYPICAL PERFORMANCE CHARACTERISTICS Ripple Rejection XC6420(VOUT=1.8V) VIN=3.0V+0.5Vp- pAC, Ta=25℃ CIN=0.1μF(ceramic), CL =1.0μF(ceramic) Ripple Rejection Rate : RR (dB) ■TYPICAL APPLICATION CIRCUITS : 150mA : 1.6V∼5.5V : 1.2V∼3.6V (±2%) 0.05V increments : 190mV ＠IOUT=150mA (VOUT=3.3V) : 55μA / ch (TYP.) : 0.1μA : 75dB@1kHz : Active High CL High Speed Auto Discharge : Current Limit 250mA (TYP.)

The P-channel MOSFET connected to the VOUT pin is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled & stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the EN pin's signal. The XC6420 needs an output capacitor (CL) for phase compensation. In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output capacitor with a capacitance value of at least 1.0μF. Also, please place 1.0μF input capacitor CL between VIN and VSS pins for stabilizing input supply voltage. The XC6420 includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows. The IC's internal circuitry can be shutdown via the signal from the EN pin with the XC6420 series. In shutdown mode, the series enables the electric charge at the output capacitor CL to be discharged via the internal switch between VOUT pin and VSS pin, and as a result the VOUT pin quickly returns to the VSS level. The EN pin is internally pulled down by a resistor. Please note that input current through a pull-down resistor exists. XC6420 series can quickly discharge the electric charge at the output capacitor (CL), when a low signal to the EN pin, which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the VOUT pin and the VSS pin (cf. BLOCK DIAGRAM). The CL discharge resistance is set to 300Ω when VIN is 5.5V (TYP.) and VOUT is 2.0V (TYP.). Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [RDCHG] and an output capacitor value (CL) as τ(τ=C x R), the output voltage after discharge via the N channel transistor is calculated by the following formulas. V = VOUT(E) x e –t/τ, or t=τIn ( VOUT(E) / V ) V : Output voltage after discharge, VOUT(E) : Output voltage, t: Discharge time, τ: CL auto-discharge resistance RDCHG×Output capacitor (CL) value C 7/26 XC6420 Series ■NOTES ON USE 1． For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded. 2. 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. 3. Where wiring impedance is high, operations may become unstable due to the noise and/or phase lag depending on output current. Please strengthen VIN and VSS wiring in particular. 4. Please wire the input capacitor (CIN) and the output capacitor (CL) as short and close to the IC as possible. 8/26 XC6420 Series ■TEST CIRCUITS ●Circuit ① VIN A EN1 IOUT1 CL =1uF (ceramic) A VOUT1 CIN =1uF (ceramic) V V IOUT2 A A VOUT2 EN2 VSS V CL=1uF (ceramic) ●Circuit ② VIN EN1 V VOUT1 CIN =1uF (ceramic) CL =1uF (ceramic) EN2 VOUT2 VSS CL =1uF (ceramic) A ●Circuit ③ CIN =1uF (ceramic) VIN EN1 VOUT1 IOUT1 CL=1uF (ceramic) A V V IOUT2 A VOUT2 EN2 VSS V CL =1uF (ceramic) 9/26 XC6420 Series ■TYPICAL PERFORMANCE CHARACTERISTICS * EN Voltage condition: Unless otherwise stated, VEN=VIN.
