XC6504 Series ETR0347-007 0.6A Ultra Low Power Consumption Small Voltage Regulator (C Capacitor-Less) L GENERAL DESCRIPTION The XC6504 series is a highly accurate CMOS voltage regulator that achieves very low supply current operation of 0.6A. Even output current is 1A (when light load), the XC6504 can provide high accurate outputs, which is ideally suited for the applications to draw less output current. The usage of super small package USPN-4B02 (0.75 x 0.95mm) and the advantage of capacitor-less stable operation can contribute the board space saving outstandingly. The IC consists of a reference voltage source, an error amplifier, a driver transistor, over-current protection circuit, and a phase compensation circuit. The device is compatible with a low ESR ceramic output capacitor CL. Moreover, the device can provide stable output even without a CL output capacitor because of the excellent internal phase compensation. Output voltage is fixed internally by laser trimming technology and can be selectable in 0.1V increments within the range of 1.1V to 5.0V. The CE function enables the device to be put into standby mode by inputting a low level signal to the CE pin thereby reducing current consumption to less than 0.1A. In the standby mode, if a CL output capacitor is used, the electric charge stored at CL can be discharged via the internal switch and as a result, the VOUT pin quickly returns to the VSS level.
