Overview
The LD1086V25 is a low drop voltage regulator produced by STMicroelectronics. This component is designed to provide up to 1.5 A of output current and is available in various packages, including TO-220, D²PAK, D²PAK/A, DPAK, and DFN8 (4x4). It is pin-to-pin compatible with older 3-terminal adjustable regulators but offers improved performance in terms of dropout voltage and output tolerance. The LD1086V25 is particularly efficient as its quiescent current flows into the load, enhancing overall efficiency.
