■GENERAL DESCRIPTION
■FEATURES
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.
Maximum Output Current : 150mA (VOUT<1.75V)
240mA (VOUT≧1.8V)
(300mA limit (TYP.))
: 200mV (IOUT=100mA)
Dropout Voltage
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.
Operating Voltage Range : 2.0V ~ 6.0V
Output Voltage Range
Highly Accuracy
: 0.9V ~ 5.0V (50mV steps)
: ±2% (VOUT>1.5)
±30mV (VOUT≦1.5V)
Low Power Consumption : 25μA (TYP.)
Standby Current
: Less than 0.1μA (TYP.)
High Ripple Rejection
: 65dB @10kHz
Operating Temperature Range : -40℃ ~ 85℃
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.
Low ESR Capacitor
Ultra Small Packages
: Ceramic capacitor
: SOT-25 (SOT-23-5)
SOT-89-5(XC6219)
USP-6B(XC6219)
The CE function allows the output of regulator to be turned off,
resulting in greatly reduced power consumption.
