The XC6501 series is a 6.0V high speed, low noise CMOS LDO regulator that can provide stable output voltages within a range of 1.2V to 5.0V (0.05V increments) even without a load capacitor CL. 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 13A (in operation) to less than 0.1A. In the stand-by mode, if a CL cap 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.
