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 includes a reference voltage source, error
amplifiers, driver transistors, current limiters and phase
compensators. The XC6219’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 XC6219 series is available in the SOT-25 (SOT-23-5), SOT-89
or USP-6B ‘chip-scale’ package. Measuring only 2.0mm x 1.8mm
the USP-6B is perfect for applications where PCB area is critical.
