High Speed LDO Regulators, High PSRR, Low noise,ME6211 Series

General Description                                  Features

 Typical Application

The ME6211  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 ME6211 series is ideal for

today’s cutting edge mobile phone. Internally the

ME6211  includes a reference voltage source, error

amplifiers, driver transistors, current limiters and

phase compensators. The ME6211’s current limiters'

foldback circuit also operates as a short protect for

the output current limiter and. the output pin. The

ME6211 series is also fully compatible with low ESR

ceramic capacitors, 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
