The CXLD64343 series are high accuracy, CMOS LDO
Voltage Regulators, offering low power, high ripple
rejection ratio and low dropout. the CXLD64343 series is ideal for today’s cutting edge mobile phone. Internally
the CXLD64343 includes a reference voltage source, error
amplifiers, driver transistors, current limiters and phase
compensators. The CXLD64343’s current limiters' foldback
circuit also operates as a short protect for the output current limiter and the output pin. The CXLD64343 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.
