ME6229 High Speed LDO Regulators,High PSRR,Low noise,ME6229 Series General Description Features The ME6229 series are highly accurate, low noise, l Maximum Output Current: 500Ma CMOS LDO Voltage Regulators. Offering low output （VIN ＝5V,VOUT ＝3.3V） noise, high ripple rejection ratio, low dropout and l Dropout Voltage: 100mV@ IOUT =100mA very fast turn-on times, the ME6229 series is ideal for l Operating Voltage Range: 2V～6.0V today’s cutting edge mobile phone. Internally the l Highly Accuracy: ±2 ％ ME6229 includes a reference voltage source, error l Low Power Consumption: 50uA （TYP. ） amplifiers, driver transistors, current limiters and l Standby Current: 0.1uA （TPY. ） phase compensators. The ME6229’s current limiters l High Ripple Rejection: 70dB@1KHz foldback circuit also operates as a short protect for （ME6229C33） the output current limiter and. the output pin. The l Low output noise: 50uVrms ME6229 series is also fully compatible with low ESR l Line Regulation: 0.05 ％（TYP. ） ceramic capacitors, reducing cost and improving l Ultra Small Packages: SOT-89-3 ，SOT-23-3 ， 5 output stability. This high level of output stability is SOT-23-5, DFN6L, SOT-353 0 maintained even during frequent load fluctuations, 3 due to the excellent transient response performance 3 Typical Application 1 and high PSRR achieved across a broad range of 5 frequencies.The CE function allows the output of l Mobile phones 3 regulator to be turned off,
