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.
