LD8105Constant Voltage and Constant Current Controller

The LD8105 is built-in with a high-accuracy 1.2V voltage reference, two op-amps and a low-side current sensing circuit in a SOT-26 package. It provides a highly integrated solution for CV (constant voltage) and CC (constant current) dual control. The LD8105 is capable to operate under temperature ranging from -40°C to 105°C.
