XC6219
Series
300mA High Speed LDO Regulators with ON/OFF Switch
ETR0307_010
■GENERAL
DESCRIPTION
The 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 XC6219 series is ideal for today’s cutting edge mobile phone.
Internally the XC6219/XC6211 includes a reference voltage source, error amplifiers, driver transistors, current limiters and
phase compensators. The XC6219/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 XC6219 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 dissipation pad for the USP-6B
package should be solder-plated in
recommended mount pattern and
metal masking so as to enhance
mounting strength and hear release.
If the pad needs to be connected to
other pins, it should be connected to
the V
SS
pin.
