产品概述 返回TOP
The CXSD62474 is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage and very low dropout voltage at up to 4 amps. It operates with VPP voltage 5V and output voltage programmable as low as 0.8V. The CXSD62474 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the CXSD62474has an enable pin to further reduce power dissipation while shutdown. The CXSD62474 provides excellent regulation over variations in line, load and temperature. The CXSD62474provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value. The CXSD62474is available in the power SOP-8 (FD) package.
