The RLCP6219 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 RLCP6219

series is ideal for today’s cutting edge mobile phone. Internally the RLCP6219 includes a reference

voltage source, error amplifiers, driver transistors, current limiters and phase compensators.

The output voltage is set by current trimming. Voltages are selectable in 100mV steps within a range

of 1.2V to 5.0V.The RLCP6219 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.
