产品概述

返回TOP

The CXLD64350 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 CXLD64350 series is ideal for today’s cutting edge mobile phone. Internally the CXLD64350 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The CXLD64350’s current limiters' foldback circuit also operates as a short protect for the output current limiter and. the output pin. The CXLD64350 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.
