Overview
The LD1086V36 is a low drop voltage regulator produced by STMicroelectronics. It is capable of providing up to 1.5 A of output current and is available in fixed output voltage configurations, including a nominal output voltage of 3.6 V for the LD1086V36 model. This regulator is pin-to-pin compatible with older 3-terminal adjustable regulators but offers improved performance in terms of dropout voltage and output tolerance. The LD1086 series is known for its high efficiency, as the quiescent current flows into the load, enhancing overall performance. The device is stable with a minimum 10 µF capacitor and is available in various packages such as TO-220, D²PAK, D²PAK/A, DPAK, and DFN8 (4x4).
