XC6604 Series ETR03071-002 0.5V Low Input, 1A High Speed LDO Regulator with Adjustable Current Limit ■GENERAL DESCRIPTION The XC6604 series is a low voltage input (0.5V) operation and provides high accuracy ±15mV / ±20mV and can supply large current efficiently due to its ultra low on-resistance even at low output voltages. The series is ideally suited to the applications which require high current in low input/output voltages and consists of a N-ch driver transistor, a voltage reference, an error amplifier, a current limiter, a fold-back circuit, a thermal shutdown (TSD) circuit, an under voltage lock out (UVLO) circuit, a soft-start circuit and a phase compensation circuit. Output voltage is selectable in 0.1V increments within a range of 0.5V to 1.8V using laser trimming technology and ceramic capacitors can be used for the output stabilization capacitor (CL). When the output current reaches the current limit, the output voltage drops as well as the output current is decreased as a function of the foldback circuit. The current limit can be adjustable with connecting a resistor to the ILIM pin. The CE function enables the output to be turned off and the series to be put in stand-by mode resulting in greatly reduced power consumption. At the time of entering the stand-by mode, the series enables the electric charge at the output capacitor (CL) to be discharged via the internal switch. As a result the VOUT pin quickly returns to the VSS level. The CE pull-down function keeps the IC to be in stand-by mode even if the CE pin is left open. ■APPLICATIONS ● Smart phones / Mobile phones ● Digital still cameras / Camcorders ● Note PCs / Tablet PCs ● E-book Readers / Electronic dictionaries ● Wireless LAN ■FEATURES Maximum Output Current : ON Resistance : 1A (1.3A Limit) 0.15Ω@VBIAS=3.6V, VOUT=1.2V Bias Voltage Range : 2.5V~6.0V Input Voltage Range : 0.5V~3.0V Output Voltage Range : 0.5V~1.8V (0.1V increments) Output Voltage Accuracy : ±0.015V@VOUT<1.2V Ripple Rejection : ±0.020V@VOUT≧1.2V 60dB@f=1kHz (VBIAS_PSRR) 75dB@f=1kHz (VIN_PSRR) Low Power Consumption : 100μA (VBIAS), 6.5μA (VIN)@VOUT=1.2V Stand-by Current : 0.01μA (VBIAS), 0.01μA (VIN) Under-voltage Lockout : 1.8V (VBIAS), 0.4V (VIN) Thermal Shutdown : 150℃@detect, 125℃@release Protection Circuit : Foldback Current Limit, TSD, UVLO Function : Soft-start CE Pull-Down (Active High) CL High Speed Discharge : -40℃~+85℃ Output Capacitor : Ceramic Capacitor Compatible (2.2μF) Packages : USP-6C, SOT-26W Environmentally Friendly : EU RoHS Compliant, Pb Free ■TYPICAL PERFORMANCE CHARACTERISTICS XC6604x121MR-G VBIAS=VCE=3.6V, VIN=1.5V CBIAS=CIN=1.0μF, CL =2.2μF, Ta=25℃ 1.4 Output Voltage: VOUT(V) ■TYPICAL APPLICATION CIRCUIT Operating Ambient Temperature 1.2 1 0.8 0.6 RLIM2=0kΩ RLIM2=22kΩ RLIM2=56kΩ RLIM2=120kΩ 0.4 0.2 0 0.0 0.5 1.0 1.5 Output Current: I OUT(A) 1/30 XC6604 Series ■BLOCK DIAGRAMS Type A Type B ■PRODUCT CLASSIFICATION ●Ordering Information XC6604①②③④⑤⑥-⑦ DESIGNATOR ITEM SYMBOL ① Type A B Refer to Selection Guide ②③ Output Voltage 05~18 e.g. 1.2V → ②=1, ③=2 ④ Output Voltage Accuracy 1 ⑤⑥-⑦ (*1) (*1) Packages (Order Unit) DESCRIPTION ±0.015V (VOUT<1.2V), ±0.020V (VOUT≧1.2V) ER-G USP-6C (3,000/Reel) MR-G SOT-26W (3,000/Reel) The “-G” suffix denotes Halogen and Antimony free as well as being fully EU RoHS compliant. ●Selection Guide TYPE SOFT-START CURRENT LIMITTER THERMAL SHUTDOWN UVLO CE PULL-DOWN RESISTOR CL AUTO DISCHARGE A Yes Adjustable Yes Yes Yes Yes B No Adjustable Yes Yes Yes Yes 2/30 XC6604 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.

The VOUT pin is then driven The output voltage at the VOUT pin is controlled and stabilized by a system of negative feedback. VBIAS pin is power supply pin for output voltage control circuit, protection circuit and CE circuit. Also, the VBIAS pin supplies some current as output current. VIN pin is connected to a driver transistor and provides output current. In order to obtain high efficient output current through low on-resistance, please take enough VGS (=VBIAS – VOUT(E)) of the driver transistor. Figure1: XC6604 Series, Type A The XC6604 series includes a combination of a fixed current limiter circuit and a foldback short-circuit protection. When the output current reaches the current limit, the output voltage drops and this operation makes the output current foldback to be decreased. The current limit can be set freely with connecting a resistor to the ILIM pin. Please note about the foldback circuit characteristics below; ●Output voltage may not rise when the output voltage is lower than 0V at the IC operation start. ●Current over the foldback current limit will not flow at the IC operation start. ●Please use type A (with soft-start time) to prevent from inrush current, because the circuit may not response to a drastic current change such as the inrush current. When the ILIM pin is left open, driver transistor will be forced off. Current Limit is calculated by the following formulas. ILIM = VOUT(T) / ( RLIM1 + RLIM2 ) × 79645.7 [A] -6 RLIM1 = VOUT(T) / ( 16.3 × 10 ) [Ω] ILIM: Current Limit VOUT(T): Nominal Output Voltage RLIM1: Internal Current Limit Resistance RLIM2: External Current Limit Resistance Figure 2: XC6604 Series, Range of adjustable current limit OUTPUT VOLTAGE RANGE ADJUSTABLE CURRENT LIMIT VOUT(T) ILIM 0.5V~1.8V 0.5A~1.3A XC6604 Series, RLIM2 Connecting 9/30 XC6604 Series ■OPERATIONAL DESCRIPTION (Continued) With the XC6604 (Type A), the inrush current (IRUSH) from VIN to VOUT for charging CL at start-up can be reduced and makes the VIN stable. As for the XC6604, the soft-start time in the type A is optimized internally. On the other hand, the type B of the XC6604 does not have the soft-start time function. When the junction temperature of the built-in driver transistor reaches the temperature limit, the thermal shutdown circuit operates and the driver transistor will be set to OFF. The IC resumes its operation when the thermal shutdown function is released and the IC’s operation is automatically restored because the junction temperature drops to the level of the thermal shutdown release temperature. When the VBIAS pin and VIN pin voltage drops, the output driver transistor is set to OFF by UVLO function to prevent false output caused by unstable operation of the internal circuitry. When the VBIAS pin voltage and the VIN pin voltage rises at release voltage, the UVLO function is released. The driver transistor is turned ON and start to operate voltage regulation. The XC6604 internal circuitry can be shutdown via the signal to the CE pin. In shutdown mode with CE low level voltage, the VOUT pin will be pulled down to the VSS level via CL discharge resistance (RDCHG) placed in parallel to R1 and R2. The CE pin has pull-down circuitry so that CE input current flows during IC operation. If the CE pin voltage is taken from VBIAS pin or VSS pin then 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 voltage is input. XC6604 series can quickly discharge the electric charge at the output capacitor (CL) via the internal transistor located between the VOUT pin and the VSS pin when a low signal to the CE pin which enables a whole IC circuit put into OFF state. When the IC is disabled, electric charge at the output capacitor (CL) is quickly discharged so that it could avoids malfunction. Discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (RDCHG) 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= CL x RDCHG), the output voltage after discharge via the internal transistor is calculated by the following formula. Please also note RDCHG is depended on VBIAS. When VBIAS is larger, RDCHG is smaller. -t/τ V = VOUT(E)×e or t=τln(VOUT(E) / V) V: Output voltage during discharge VOUT(E): Initial Output voltage t: Discharge time τ: CL×RDCHG With the XC6604 series, a stable output voltage is achievable even if used with low ESR capacitors, as a phase compensation circuit is built-in. The output capacitor (CL) should be connected as close to VOUT pin and VSS pin to obtain stable phase compensation. Values required for the phase compensation are as the table below. For a stable power input, please connect a bias capacitor (CBIAS) between the VBIAS pin and the VSS pin. Also, please connect an input capacitor (CIN) between the VIN pin and the VSS pin. In order to ensure the stable phase compensation while avoiding run-out of values, please use the capacitor (CBIAS, CIN and CL) which does not depend on bias or temperature too much. The table below (Figure 3) shows recommended values of CBIAS, CIN and CL. Figure 3: Recommended Values of CBIAS, CIN and CL (MIN.)

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 keep the resistance low for the VBIAS, VIN and VSS wiring in particular. 3. Please wire the CBIAS, CIN and CL as close to the IC as possible. 4. Capacitances of these capacitors (CBIAS, CIN, CL) are decreased by the influences of bias voltage and ambient temperature. Care shall be taken for capacitor selection to ensure stability of phase compensation from the point of ESR influence. 5. When it is used in a quite small input / output dropout voltage, output may go into unstable operation. it in production. Please test it thoroughly before using 6.
