■GENERAL
DESCRIPTION
The XC6211/XC6219 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 XC6211/6219 series is ideal for today’s cutting edge mobile
phone.
Internally the XC6211/6219 includes a reference voltage
source, error amplifiers, driver transistors, current limiters and
phase compensators. The XC6211/6219’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 XC6211/6219 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.
