1 High Speed LDO Regulators, High PSRR, Low noise, Series General Description The series are highly accurate, low noise, CMOS LDO Voltage Regulators. Offering low output noise, high ripple rejection ratio, low dropout and very fast turn-on times, the series is ideal for today s cutting edge mobile phone. Internally the includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The s current limiters' foldback circuit also operates as a short protect for the output current limiter and. the output pin. The series is also fully compatible with low ESR ceramic capacitors, Features Maximum Output Current: 350mA (V IN =4.3V,V OUT =3.3V) : 100mV@ I OUT =100mA Operating Voltage Range: 2V~6.0V Highly Accuracy: ±2% Low Power Consumption: 50uA(TYP.) Standby Current: 0.1uA(TPY.) High Ripple (C33) Low output noise: 50uVrms : 0.05%(TYP.) reducing cost and improving output stability. This high level of output stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies.the CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption.
