XC6503Series

ETR0346-009

C_LCapacitor-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 C_L. The devices are available in fixed output voltage from 1.2V to 5.0V in 0.05V increments

The C_Lcapacitor-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.

When a C_Lcapacitor is used, the IC can discharge the electric charge stored at the output capacitor through the internal

switch while in standby state, and as a result the V_OUTquickly returns to the V_SSlevel.
