XC6210 Series ETR0317 004 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 Torexs 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 0.05V 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. FEATURES APPLICATIONS Maximum Output Current : More than 700mA CD-ROMs, CD-R / RW drive (800mA limit, TYP.) DVD drive (1.6V<VOUT(T)<5.0V) Dropout Voltage : 50mV 100mA HDD drive : 100mV 200mA Cameras, Video recorders Operating Voltage Range : 1.5V ~ 6.0V Output Voltage Range : 0.8V ~ 5.0V (0.05V increments) Portable AV equipment Highly Accurate : +2%(The setting voltage accuracy) Battery powered equipment Low Power Consumption : 35 A (TYP.) High Ripple Rejection : 60dB 1kHz Operational Ambient Temperature : - 40 ~ 85 CMOS Low ESR Capacitor Compatible Packages : SOT-25 SOT-89-5 USP-6B Environmentally Friendly : EU RoHS Compliant, Pb Free TYPICAL PERFORMANCE TYPICAL APPLICATION CIRCUIT CHARACTERISTICS Dropout Voltage vs. Output Current 1/22 XC6210 Series PIN CONFIGURATION VOUT VIN VOUT NC 5 4 5 4 *The dissipation pad for the USP-6B package should be solder-plated in recommended mount pattern and metal masking so as to enhance mounting 1 2 3 strength and heat release. If the VIN VSS CE 1 2 3 pad needs to be connected to CE VSS NC other pins, it should be connected USP-6B to the VSS pins.
