XC6501P

XC6501 ETR03037-014b 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. ■APPLICATIONS ●Smart phones / Mobile phones ●Portable games ●Modules (wireless, cameras,etc.) ●Bluetooth ●Digital-TV tuners ■FEATURES Maximum Output Current : 200mA Operating Voltage Range Output Voltage Range Dropout Voltage Low Power Supply Stand-by Current : 1.4V ~ 6.0V 2.0V ~ 5.0V (±1%) (*1) : 1.2V ~ 1.95V (±0.02V) (*1) : 150mV＠IOUT=100mA, VOUT=2.8V : 13μA ＠VOUT=2.8V : Less than 0.1μA Ripple Rejection Protection Circuits : 50dB＠...
