The KX6211 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 KX6211 series is ideal for
today’s cutting edge mobile phone. Internally the
KX6211 includes a reference voltage source, error
amplifiers, driver transistors, current limiters and
phase compensators. The KX6211’s current limiters'
foldback circuit also operates as a short protect for
the output current limiter and. the output pin. The
KX6211 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
regulator to be turned off, resulting in greatly reduced
power consumption.
