The CXLD64148 CXLD64148A is a dual-channel regulator with reset function (specific voltage monitoring), and internal delay circuit, set to detect 3.9V or 4.2V. Maximum input voltage is 6V, output1 and output2 deliver up to 500mA. VOUT1 typical dropout voltage is 550mV at 500mA loading and VOUT2 typical dropout voltage is 630mV at 500mA loading. Design with an internal Pchannel MOSFET pass transistor, the CXLD64148/A maintains a low supply current. Other features include, thermal-shutdown protection, current limit protection to ensure specified output current. The CXLD64148/A come in miniature SOP-8 and SOP-8-P packages.
