Constant Voltage and Constant Current Controller

Rev. 00

General Description

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.
