XC6419 Series ETR0338-003 Dual LDO Regulator (ch1=300mA, ch2=100mA) with ON/OFF Switch ■GENERAL DESCRIPTION The XC6419 series is a dual CMOS LDO regulator. The series features high accuracy, low output noise, high ripple rejection and low dropout and consists of a voltage reference, error amplifier, driver transistor, current limiter, thermal shutdown circuit and phase compensation circuit. Each output voltage is set independently by laser trimming and selectable in 0.05V increments within a range of 0.8 to 5.0V. The EN function turns each output of the two regulators off independently. In this state, the electric charge at the output capacitor (CL) is discharged via the internal auto-discharge switch, and as a result the VOUT voltage quickly returns to the VSS level. The output stabilization capacitor (CL) 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. VR1 and VR2 are completely isolated so that a cross talk during load fluctuations is minimized. ■FEATURES ■APPLICATIONS ● Mobile phones ● Cordless phones, Wireless communication equipment ● Portable games Input Voltage Range : 1.5~6.0V Maximum Output Current : ch1.300mA / ch2.100mA Output Voltage Range : : : 0.8~5.0V ±1% (XC6419A/B) ±20mA@ VOUT≦2.0V ±2% (XC6419C/D) ±30mA@ VOUT≦1.5V ch1.115mV@IOUT=200mA ch2.115mV@IOUT=50mA ch1.28μA / ch2.23μA Stand-by Current : Less than 0.1μA Ripple Rejection : 60dB@f=1kHz Current Limit : ch1.400mA / ch2.150mA : USP-6C, SOT-26 Output Accuracy ● Digital still cameras, Digital video cameras ● Portable audio equipment ● PDAs Dropout Voltage (VOUT=2.8V) Low Power Consumption : Low ESR Capacitor CL High Speed Discharge Small Packages ■TYPICAL APPLICATION CIRCUITS ■TYPICAL PERFORMANCE CHARACTERISTICS 6 VOUT V=2.8V OUT=2.8V 5 2 85℃ 25℃ -40℃ 350 4 3 DropoutVoltage Dropout Voltage: :Vdif Vdif[mV] (mV) 1 ●Dropout Voltage vs. Output Current 400 ch2 Maximum Output Current 2CH最大出力電流 300 100mA ch1 Maximum Output Current 1CH最大出力電流 250 300mA 200 ch2 2CH 150 100 ch1 1CH 50 0 0 50 100 150 200 250 300 Output Current :: IOUT (mA) OUT [mA] OutputCurrent 1/29 XC6419 Series ■PIN CONFIGURATION *The dissipation pad for the USP-6C package should be solder-plated in recommended mount pattern and metal masking so as to enhance mounting strength and heat release. If the pad needs to be connected to other pins, it should be connected to the VSS (No. 4) pin. ■PIN ASSIGNMENT PIN NUMBER SOT-26 PIN NAME USP-6C FUNCTIONS 1 3 EN1 : ON/OFF Control 1 2 2 VIN : Power Input 3 1 EN2 : ON/OFF Control 2 4 6 VOUT2 : Output 2 5 6 4 5 VSS VOUT1 : Ground : Output 1 ■PRODUCT CLASSIFICATION ●Ordering Information XC6419①②③④⑤⑥ DESIGNATOR DESCRIPTION A B C D A B C D ① VR1 ② VR2 ③④ Output Voltage ⑤ Packages ⑥ Device Orientation DESIGNATOR ③④ ③④ VR1 01 02 03 04 05 06 07 08 09 10 1.80 1.20 1.80 1.50 2.85 1.80 3.00 2.80 1.20 1.10 SYMBOL 01~ M E R L DESCRIPTON : EN High Active without CL auto discharge (Accuracy:1%) : EN High Active with CL auto discharge (Accuracy:1%) : EN High Active without CL auto discharge (Accuracy:2%) : EN High Active with CL auto discharge (Accuracy:2%) : EN High Active without CL auto discharge (Accuracy:1%) : EN High Active with CL auto discharge (Accuracy:1%) : EN High Active without CL auto discharge (Accuracy:2%) : EN High Active with CL auto discharge (Accuracy:2%) : Sequential number showing VR1 and VR2 voltage combination VR1 range: 0.8 ~ 5.0V , VR2 range : 0.8 ~ 5.0V (0.05V increments) Refer to the table below : SOT-26 : USP-6C : Embossed tape, standard feed : Embossed tape, reverse feed VR2 ③④ VR1 VR2 ③④ VR1 VR2 2.80 2.90 1.80 2.70 2.85 3.30 3.00 1.80 1.20 1.30 11 12 13 14 15 16 17 18 19 20 1.30 2.80 2.50 3.00 1.20 2.80 3.30 3.10 2.80 1.30 1.50 2.80 3.30 3.30 1.80 3.30 3.30 3.10 1.50 2.80 21 22 23 24 25 26 27 28 29 30 1.50 1.80 1.85 1.85 2.60 1.50 2.00 3.30 3.30 2.10 2.80 3.00 2.80 3.30 2.80 1.50 3.00 1.80 1.75 4.10 *For other combinations, please ask Torex sales contacts. 2/29 XC6419 Series ■BLOCK DIAGRAMS * Diodes inside the circuits are ESD protection diodes and parasitic diodes. ■ABSOLUTE MAXIMUM RATINGS Ta=25℃ PARAMETER Input Voltage Output Current Output Voltage 1 / Output Voltage 2 EN1/EN2 Input Voltage Power Dissipation USP-6C SOT-26 Operating Temperature Range Storage Temperature Range SYMBOL VIN IOUT1+IOUT2 VOUT1 /VOUT2 VEN1 /VEN2 Pd Topr Tstg RATINGS - 0.3 ~ + 6.5 500 (*1) VSS - 0.3 ~ VIN + 0.3 VSS - 0.3 ~ + 6.5 120 (*2) 1000 (PCB mounted) 250 - 40 ~ + 85 - 55 ~ + 125 UNITS V mA V V mW ℃ ℃ *1: Please use within the range of Pd > { (VIN-VOUT1)×IOUT1 + (VIN-VOUT2)×IOUT2 } *2: This power dissipation figure shown is PCB mounted and is for reference only.

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 and 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. <CL Auto-Discharge Function> XC6419xB/Bx/xD/Dx series can quickly discharge the electric charge at the output capacitor (CL) through the N-channel transistor located between the VOUT pin and the VSS pin (refer to the BLOCK DIAGRAM) when a low level signal is applied to the EN pin. The CL discharge resistance is set to 550Ω when VIN is 6.0V (TYP.) and VOUT is 4.0V (TYP.). Moreover, discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] 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 formulae. –t/ V = VOUT x e τ, or t = τln(VOUT (E) / V) where V: Output voltage after discharge, VOUT (E): Output voltage, t: Discharge time, τ: CL auto-discharge resistance RDCHG×CL capacitance C CL high-speed discharge function can be set by each regulator. <Current Limiter, Short-Circuit Protection> The XC6419 series includes a fold-back circuit, which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fold-back circuit operates and output voltage drops. As a result of this drop in output voltage, output current also decreases. When the output pin is shorted, the output current flows go down to 30mA / ch1 and 15mA/ch2 (TYP.). <EN Pin> Each regulator can be shut-downed via the signal from the EN pin with the XC6419 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via Rx1 & Rx2. However, as for the XC6419xB/Bx/xD/Dx series, the CL auto-discharge resistor is connected in parallel to Rx1 and Rx2 while the power supply is applied to the VIN pin. Therefore, time until the VOUT pin reaches the VSS level becomes short. The output voltage becomes unstable, when the EN pin is open. If this IC is used with the correct output voltage for the EN pin, the logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry when medium 8/29 XC6419 Series ■OPERATIONAL DESCRIPTION (Continued) <Input and Output Capacitor> The XC6419 needs an output capacitor CL for phase compensation. The requested capacitance values are described in the table below. The device may go into unstable operation when the output capacitance reduction happens as a result of bias or temperature drift. Please choose a capacitor with less influence from temperature and bias. Also, please place 1.0μF input capacitor CIN between VIN and VSS pins for stabilizing input supply voltage. SETTING VOLTAGE OUTPUT CAPACITOR 0.8V∼1.15V CL≧2.2μF 1.2V∼5.0V CL≧1.0μF ■NOTES ON USE 1. Please use this IC within the stated absolute maximum ratings. 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 CIN and the output capacitor CL as close to the IC as possible. 9/29 XC6419 Series ■TEST CIRCUITS ●Circuit ① ●Circuit ② ●Circuit ③ 10/29 XC6419 Series ■TYPICAL PERFORMANCE CHARACTERISTICS * EN Voltage condition: Unless otherwise stated, VEN=VIN while the other channel is turned off ((VEN=VSS).
