XC6401HF01DR

XC6401 Series Dual LDO Regulators, Low ESR Cap. Compatible ETR0309_005 ■GENERAL DESCRIPTION The XC6401 series are highly accurate, Dual, low noise, CMOS LDO voltage regulators. Performance features of the series includes low output noise, high ripple rejection ratio, low dropout and very fast turn-on times. The XC6401 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators internally. The XC6401’s current limiters' foldback circuit also operates as a short protect for the output current limiter. The output voltage for each regulator is set independently by laser trimming. Voltages are selectable in 50mV steps within a range of 0.8V to 5.0V. The XC6401 series is also fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. The XC6401 series is available in the SOT-26W or USP-6B, USP-6C ‘chip-scale’ package. ■APPLICATIONS ●Mobile Phones ●Cordless phones and radio communication equipment ●Portable games ●Cameras, Video recorders ●Portable Audio Equipment ●PDAs ■FEATURES Maximum Output Current Dropout Voltage Operating Voltage Range Output Voltage Range Highly Accurate Low Power Consumption Standby Current High Ripple Rejection : More than 150mA (300mA limit) : 100mV @100mA : 1.5V ~ 6.0V : 0.8V~5.0V (50mV increments) : ±2% (VOUT>1.5V) : ±30mV (VOUT≦1.5V) : 25μA (TYP.) : Less than 0.1μA (TYP.) : 70dB @1kHz Operating Temperature Range : -40℃ ~ +85℃ Low ESR Capacitor Compatible : Ceramic capacitor Low Output Noise Ultra Small Packages : SOT-26W,USP-6B,USP-6C ■TYPICAL APPLICATION CIRCUITS ■TYPICAL PERFORMANCE CHARACTERISTICS ●SOT-26W EN1 VOUT1 6 1 2 CL1 1uF ●Interactive Load Transient Response VIN EN2 VSS VOUT2 5 CIN 1uF 4 3 CL2 1uF ●USP-6 1 2 CIN 1uF 3 EN2 VOUT2 VIN VOUT1 EN1 VSS 6 5 4 CL1 1uF CL2 1uF 1/24 XC6401 Series ■PIN CONFIGURATION VOUT1 6 6 VSS 5 VOUT2 4 1 EN1 2 VIN SOT-26W (TOP VIEW) 3 EN2 USP-6B / 6C (BOTTOM VIEW) *The dissipation pad for the USP-6B/C packages 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 pin. ■PIN ASSIGNMENT PIN NUMBER SOT-26W USP-6B/C 1 3 2 2 3 1 4 6 5 4 6 5 PIN NAME EN1 VIN EN2 VOUT2 VSS VOUT1 FUNCTION ON/OFF Control 1 Power Input ON/OFF Control 2 Output 2 Ground Output 1 ■PRODUCT CLASSIFICATION ●Selection Guide The following options for the Regulator 1, 2, the EN pin logic, internal pull-up / down are available. ●Ordering Information XC6401①②③④⑤⑥ DESIGNATOR DESCRIPTION Regulator1, EN type SYMBOL E F G H E F G H 01~ M ⑤ Packaging Types D E ⑥ Device Orientation R L DESCRIPTION : High Active with pull-down resistor : High Active with no pull-down resistor : Low Active with pull-up resistor : Low Active with no pull-up resistor : High Active with pull-down resistor : High Active with no pull-down resistor : Low Active with pull-up resistor : Low Active with no pull-up resistor : Internally set sequential number relating output voltage of each regulators Regulator 1 Output Voltage Range: 0.8 ~ 5.0 V (50mV increments) Regulator 2 Output Voltage Range: 0.8 ~ 5.0 V (50mV increments) : SOT-26W : USP-6B : USP-6C : Embossed tape, standard feed : Embossed tape, reverse feed ① ② Regulator2, EN type ③④ Output Voltage 2/24 XC6401 Series ■ABSOLUTE MAXIMUM RATINGS PARAMETER Input Voltage Output Current Output Voltage EN Pin Voltage SOT-26W Power Dissipation USP-6B USP-6C Operating Temperature Range Storage Temperature Range * Sum of IOUT1 and IOUT2. ** Pd=(VIN-VOUT1)xIOUT1+(VIN-VOUT2)xIOUT2 Ta = 25℃ RATINGS 6.5 700 VSS -0.3 ~ VIN +0.3 VSS -0.3 ~ 6.5 250 100 100 -40 ~ +85 -55 ~ +125 UNITS V mA V V mW ℃ ℃ SYMBOL VIN IOUT1 + IOUT2 VOUT VEN Pd Topr Tstg ■ELECTRICAL CHARACTERISTICS XC6401FFxx Regulator 1, Regulator 2 PARAMETER Output Voltage (*3) Maximum Output Current Load Regulation Dropout Voltage Supply Current Standby Current Line Regulation (*7) Input Voltage Output Voltage SYMBOL VOUT (E) IOUTMAX △VOUT Vdif1 Vdif2 ISS ISTB △VOUT △VIN ・ Ta=25℃ CONDITIONS VIN=VOUT (T) + 1.0V IOUT=30mA VIN=VOUT (T) + 1.0V 1mA≦IOUT≦100mA IOUT=30mA IOUT=100mA VIN=VEN=VOUT (T) + 1.0V, IOUT=0mA VIN=VOUT (T) + 1.0V, VEN=VSS VOUT(T)+1.0V≦VIN≦6.0V VEN=VIN, IOUT=30mA IOUT=30mA -40℃≦Topr≦85℃ VIN=[VOUT(T)+1.0]VDC+0.5Vp-pAC IOUT=30mA, f=1kHz VIN=VOUT (T) + 1.0V, VEN=VIN VIN=VOUT (T) + 1.0V, VEN=VIN MIN. 0.98 150 TYP.
