产品概述 返回TOP
The CXSD62468 CXSD62469 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 2 amps. It operates with a VIN as low as 1.4V and VPP voltage 5V with output voltage programmable as low as 0.8V. The CXSD62468 CXSD62469 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the CXSD62468 CXSD62469 has an enable pin to further reduce power dissipation while shutdown. The CXSD62468 CXSD62469 provides excellent regulation over variations in line, load and temperature. The CXSD62468 CXSD62469 provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value. The CXSD62468 CXSD62469is available in the power TSOT-23-6, SOP-8(FD), MSOP-10(FD) and TDFN3X3-10 package. It is available with 2.5V internally preset outputs that are also adjustable using external resistors.
