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.
