XC6219/XC6211 Series
ETR0307_008
High Speed LDO Regulators, Low ESR Cap. Compatible, ON/OFF Switch
GENERAL DESCRIPTION
The XC6219/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 XC6219/6211 series is ideal for todays cutting edge mobile
phone.
Internally the XC6219/6211 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase
compensators. The XC6219/6211s 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 XC6219/6211 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.
