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 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. When a CL capacitor 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 VOUT quickly returns to the VSS level.

The XC6501 series is a high-speed, low-noise CMOS LDO regulator that can provide stable output voltages even without a load capacitor. This is possible because phase compensation is carried out internally unlike other LDOs where it is done externally. The series consists of a reference voltage source, driver transistor, error amplifier, current limit circuit, and phase compensation circuit. The CE function enables the circuit to be put into stand-by mode by inputting a low level signal to the CE pin thereby reducing current consumption from an already low 13μA (in operation) to less than 0.1μA. In the stand-by mode, if a CL capacitor is used, the electric charge stored at CL can be discharged via the internal auto-discharge switch and as a result, the VOUT pin quickly returns to the VSS level. The current limit fold-back circuit operates as a short circuit protection and a current limiter function for the output pin.
