XC6211 Series
Low ESR Cap. Compatible, On / Off Switch
High Speed LDO Regulator
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.

Selection Guide
The following options for the CE pin logic and internal pull-up/down are available:
Active 'High' + no pull-down resistor built-in (standard)
Active 'High' + 2.0M
pull-down resistor built-in <between CE-VSS> (semi-custom)
Active 'Low' + no pull-up resistor built-in (semi-custom)
Active 'Low' + 2.0M
pull-up resistor built-in <between VIN-CE> (semi-custom)
Note: *With the pull-up resistor or pull-down resistor built-in types,
the supply current during operation will increase by VIN / 2.0M

(NOTE 1) VOUT(T)=Specified Output Voltage
(NOTE 2) VOUT(E)=Effective Output Voltage
(I.e. the output voltage when "VOUT(T)+1.0V" is provided at the VIN pin while maintaining a certain IOUT value).
(NOTE 3) Vdif={VIN1(NOTE5)-VOUT1(NOTE4)}
(NOTE 4) VOUT1=A voltage equal to 98% of the Output Voltage whenever an amply stabilized IOUT {VOUT(T)+1.0V} is input.
(NOTE 5) VIN1=The Input Voltage when VOUT1 appears as Input Voltage is gradually decreased.
(NOTE 6) Unless otherwise stated, VIN=VOUT(T)+1.0V
Dropout Voltage
* The input voltage 2.0V (Min.) is needed to operate the series. When the output voltage is less than 2.0V,
2.0V-V
