General Description
The XC6211 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 XC6211 series
is ideal for today’s cutting edge mobile phone.
Internally the XC6211 includes a reference voltage source, error
amplifiers, driver transistors, current limiters and phase
compensators. The XC6211’s current limiters' foldback circuit also
operates as a short protect for the output current limiter and the
output pin.
The output voltage is set by laser trimming. Voltages are
selectable in 50mV steps within a range of 0.9V to 5.0V. The
XC6211 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.
The XC6211 series is available in the SOT-23-5 package.
