XC6219 Series ETR0307 010 300mA High Speed LDO Regulators with ON/OFF Switch 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 todays cutting edge mobile phone. Internally the XC6219/XC6211 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The XC6219/XC6211s 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.
