GENERAL DESCRIPTION

The XC6503 series is a 500mA high speed CMOS LDO regulator that can provide stable output voltages even without a load

externally. It results in saving board design space. The current limit fold-back circuit and thermal shutdown circuit work as

protection circuit. The XC6503P is a 3-Terminal regulator and the XC6503D has a chip enable function, which enables the

entire circuit to be turned off by a low level input signal to the CE pin.
