General Description

Typical Applications

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-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.
