一.产品概述
The CXLD6406 series are high performance linear voltage regulators that provide ultra low-dropout voltage, high output current in lowest output voltage. It operates from an input of 1.4V to 5.5V and provides output current up to 2A thus is suitable to drive digital circuits requiring low voltage at high currents.
The CXLD6406 has superior regulation over variations in line and load. Also it provides fast respond to step changes in load. Other features include over-current and overtemperature protection. The adjustable version has enable pin to reduce power consumption in shutdown mode. The devices are available ADJ output , and via exteral R adjust output voltage from 0.6V to Vin-0.3V, 0.6V is the reference voltage. The CXLD6406 have enable function , that is good for poratble system for main chip on and off. In order to have lower dropout and bigger current output Ven should 0.8~1.0V higher than Vin, but can work if same. Power pad sop8 can output over 2A and 1.8A without the pad.
