XC6501
ETR03037-010
200mA High Speed LDO Regulator, Output Capacitor-Less, Low Power Consumption
■GENERAL DESCRIPTION
The XC6501 series is a high speed, low noise CMOS LDO regulator that can provide stable output voltages 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 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.
