XC6503 Series ETR03046-009b CL Capacitor-Less 500mA Low Power Consumption High Speed LDO Regulator ■GENERAL DESCRIPTION The XC6503 series is a 500mA high speed CMOS LDO regulator that can provide stable output voltages even without a load capacitor CL. The devices are available in fixed output voltage from 1.2V to 5.0V in 0.05V increments The CL capacitor-less is possible because phase compensation is carried out internally unlike other LDOs where it is done 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 XC6503A/B/C/D has a chip enable function, which enables the entire circuit to be turned off by a low level input signal to the CE pin.
