XC6210 Series ETR0317_002 High Current, High Speed LDO Regulators ■GENERAL DESCRIPTION The XC6210 series are precise, low noise, high current, positive voltage low dropout regulators. They are fabricated using Torex’s CMOS process. The series features a voltage reference, an error amplifier, a current limiter, and a phase compensation circuit plus a driver transistor. With a low ON resistance driver transistor built into, batteries can be used until input-output voltage differential is minimal and can accordingly be used for a longer time. The series is also compatible with low ESR ceramic capacitors which give added output stability. The output voltage of the LDO is selectable in 50mV increments within the range of 0.8V to 5.0V. The current limiter's foldback circuit also operates as the output current limiter and the output pin protection. The IC's internal regulator circuit can be placed in stand-by mode via the CE function. In the stand-by mode, power consumption is greatly reduced. ■APPLICATIONS ●CD-ROMs, CD-R / RW drive ●DVD drive ●HDD drive ●Cameras, Video recorders ●Portable AV equipment ●Battery powered equipment ■TYPICAL APPLICATION CIRCUIT ■FEATURES Maximum Output Current : More than 700mA (800mA limit, TYP.)

The P-channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled & stabilized by negative feedback. The constant current limit circuit and short circuit protection operate in relation to the level of output current. <Low ESR Capacitor> With the XC6210 series regulator, a stable output voltage is achievable even if low ESR capacitors are used, as a phase compensation circuit is built into the regulator. In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) be connected as close as possible, between the output pin (VOUT) and the VSS pin. Please use an output capacitor (CL) with a capacitance, based on the chart below. We also suggest an input capacitor (CIN) of 1μF: this should be connected between VIN and VSS in order to stabilize input power source. Output Capacitor Corresponding Chart VOUT CL 0.8V ~ 1.45V More than 6.8μF 1.5V ~ 1.75V More than 4.7μF 1.8V ~ 5.0V More than 1.0μF <Current Limiter, Short-Circuit Protection> The XC6210 series regulator offers a combination of current limit and short circuit protection by means of a built-in fixed current limiter circuit and a foldback circuit. 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, the output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows. <CE Pin> The IC's internal regulator circuitry can be shut down via the signal from the CE pin with the XC6210 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. Options are available for the CE pin logic (See the product classification). Note that as the XC6210B types are 'High Active / No Pull-Down', operations will become unstable with the CE pin open. Although the CE pin is equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry if a voltage other than VIN or VSS is applied. ■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 strengthen VIN and VSS wiring in particular. 3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. Should rapid input fluctuation or load fluctuation occur, please increase the capacitor value such as CIN or CL to stabilize the operation. 8/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (1) Output Voltage vs. Output Current 9/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (2) Output Voltage vs. Input Voltage 10/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (3) Dropout Voltage vs. Output Current 11/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (4) Supply Current vs. Input Voltage (5) Output Voltage vs. Ambient Temperature 12/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (6) Supply Current vs. Ambient Temperature (7) CE Pin Threshold Voltage vs. Ambient Temperature 13/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (8) Input Transient Response 1 14/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (9) Load Transient Response 15/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (10) Ripple Rejection Rate 16/22 XC6210 Series ■TYPICAL PERFORMANCE CHARACTERISTICS (Continued) (11) Input Transient Response 2 17/22 XC6210 Series ■PACKAGING INFORMATION ●SOT-25 (SOT-23-5) ●SOT-89-5 ●USP-6B * Pin no. 1 is thicker than other pins. 18/22 XC6210 Series ■PACKAGING INFORMATION (Continued) ●USP-6B Recommended Pattern Layout ●USP-6B Recommended Metal Mask Design 19/22 XC6210 Series ■MARKING RULE ●SOT-25 ①Represents product series MARK PRODUCT SERIES 0 XC6210xxxxxx ②Represents CE function MARK PRODUCT SERIES VOLTAGE= VOLTAGE= VOLTAGE= VOLTAGE= 0.1~3.0V 3.1~6.0V 0.15~3.05V 3.15~6.05V V A E L XC6210Axxxxx X B F M XC6210Bxxxxx Y C H N XC6210Cxxxxx Z D K P XC6210Dxxxxx ●SOT-89-5 ③Represents output voltage MARK SOT-89-5 (TOP VIEW) OUTPUT VOLTAGE (V) MARK OUTPUT VOLTAGE (V) 0 - 3.1 - 3.15 F 1.6 4.6 1.65 4.65 1 - 3.2 - 3.25 H 1.7 4.7 1.75 4.75 2 - 3.3 - 3.35 K 1.8 4.8 1.85 4.85 3 - 3.4 - 3.45 L 1.9 4.9 1.95 4.95 4 - 3.5 - 3.55 M 2.0 5.0 2.05 - 5 - 3.6 - 3.65 N 2.1 - 2.15 - 6 - 3.7 - 3.75 P 2.2 - 2.25 - 7 0.8 3.8 - 3.85 R 2.3 - 2.35 - 8 0.9 3.9 0.85 3.95 S 2.4 - 2.45 - 9 1.0 4.0 0.95 4.05 T 2.5 - 2.55 - A 1.1 4.1 1.15 4.15 U 2.6 - 2.65 - B 1.2 4.2 1.25 4.25 V 2.7 - 2.75 - C 1.3 4.3 1.35 4.35 X 2.8 - 2.85 - D 1.4 4.4 1.45 4.45 Y 2.9 - 2.95 - E 1.5 4.5 1.55 4.55 Z 3.0 - 3.05 - ④Represents production lot number 0 to 9, A to Z reverse character 0 to 9, A to Z repeated (G, I, J, O, Q, W excepted) 20/22 XC6210 Series ■MARKING RULE (Continued) ●USP-6B ①②Represents product series MARK ① ② 1 0 PRODUCT SERIES XC6210xxxxxx ③Represents CE Function USP-6B (TOP VIEW) MARK TYPE PRODUCT SERIES A High Active With Pull-Down Resistor XC6210AxxxDx B High Active With No Pull-Down Resistor XC6210AxxxDx C Low Active With Pull-Up Resistor XC6210AxxxDx D Low Active With No Pull-Up Resistor XC6210AxxxDx S Custom XC6210AxxxDx ④Represents the integer number of output voltage MARK VOLTAGE (V) PRODUCT SERIES 3 3.3 XC6210x3xxDx 5 5.0 XC6210x5xxDx ⑤Represents the decimal point of output voltage MARK 0 VOLTAGE PRODUCT (V) SERIES x.0 XC6210xx02Dx VOLTAGE PRODUCT (V) SERIES A x.05 XC6210xx0ADx MARK 1 x.1 XC6210xx12Dx B x.15 XC6210xx1ADx 2 x.2 XC6210xx22Dx C x.25 XC6210xx2ADx 3 x.3 XC6210xx32Dx D x.35 XC6210xx3ADx 4 x.4 XC6210xx42Dx E x.45 XC6210xx4ADx 5 x.5 XC6210xx52Dx F x.55 XC6210xx5ADx 6 x.6 XC6210xx62Dx H x.65 XC6210xx6ADx 7 x.7 XC6210xx72Dx K x.75 XC6210xx7ADx 8 x.8 XC6210xx82Dx L x.85 XC6210xx8ADx 9 x.9 XC6210xx92Dx M x.95 XC6210xx9ADx ⑥Represents production lot number 0 to 9, A to Z repeated (G, I, J, O, Q, W, excepted) Note: No character inversion used. 21/22 XC6210 Series 1.
